search for: deallocated

I repeatedly get a popup when running an old Windows 3.1 game on Ubuntu, Wine 0.9.59. It reads ... Memory BUG Deallocation of a locked memory block I can usually continue OK, but it's very annoying. Is there anything I can do about it? Thanks.

...tx = Mod->getContext(); delete Mod; std::lock_guard<std::mutex> Lock(Ctx->getMutex()); if (Ctx.getNumModules()) delete Ctx; Another option would be to invert the ownership model and say that each Module shares ownership of its LLVMContext. That way LLVMContexts would be automatically deallocated when the last module using them is destructed (providing no other shared_ptrs to the context are held elsewhere). There are other possible approaches (e.g. side tables for the mutex and module count) but before I spent too much time on it I wanted to see whether anyone else has encountered these i...

LTOCodeGenerator::addModule (which is wrapped by lto_codegen_add_module) takes an LTOModule as an argument and links the latter's llvm::Module into its own. It does not change the latter's llvm::Module. The lto_module_dispose API call destroys an LTOModule. This frees the LTOModule's llvm::Module, but also invalidates strings returned by, e.g., lto_module_get_symbol_name. I propose

...allocate bit in the Write Zeroes command) is that the only difference between Deallocate = 1 and 0 is that the device "should" versus "may" (no "shall" on either side) deallocate the corresponding blocks, but only if the device supports reading 0s back after blocks are deallocated. If the device does not support reading 0s after deallocation, it is not allowed to deallocate blocks as part of a Write Zeroes command regardless of the setting of the Deallocate bit. Some similar wording could probably be added to the virtio spec to clarify the meaning of unmap, although I would...

Hi, So 9316 works and 9320 doesn't? How about latest SVN. I just ran everything in valgrind and saw no error at all. Can you give more info on how to reproduce (with speexenc)?

When updating the speex sources from svn tree, I found that the following revision has corrupted the deallocation (segmentation fault): ------------------------------------------------------------------------ r9320 | jm | 2005-05-27 15:05:05 -0300 (Fri, 27 May 2005) | 2 lines Proper de-allocation When compiling with the 9316, everything works fine. but when I update with later

...vm::JITMemoryManager and do something like this. I've been trying to work with this solution, but it does pose a problem. The problem is that we use an ExecutionEngine and set a memory manager with setJITMemoryManager on EngineBuilder. The problem is that this means when the ExecutionEngine is deallocated, it end up deallocating the memory manager. I can understand doing this when the code sets up it's own memory manager, but with an external memory manager, I'd expect LLVM not to deallocate that object for me. Is there a way to prevent this from happening? I can't keep the ExecutionEng...

Up until now, freeing payloads on remote MST hubs that just had ports removed has almost never worked because we've been relying on port validation in order to stop us from accessing ports that have already been freed from memory, but ports which need their payloads released due to being removed will never be a valid part of the topology after they've been removed. Since we've

...ou'd need to know that the parameter was not also aliased with another argument (or had not been captured). Another analysis would need to provide this kind of information. Also, just because a function does not, directly or indirectly, call free does not mean that it cannot cause memory to be deallocated. The function might communicate (synchronize) with another thread causing that other thread to delete the memory. For this reason, to use dereferenceable as we currently do, we also need to know that the function does not synchronize with any other threads. To solve this problem, like nofree, I pro...

Hi all, So I have finally finished the v1 of reflink for ocfs2. It has some bugs that I am still investigating, but the schema is almost there. So I'd like to send it out first for review. And Tristan and I will continue to work on the stability of the code. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink. For the design doc, please

We are currently using the JIT (non-MC) to implement a REPL-like shell that needs to run in a long-lived process. During development, we noticed substantial memory-growth with increased lifetime of the JIT. In trying to eliminate that continuous memory growth, we did a few things, including making LLVMContext collect and free unused constants (detected by Value::uses_empty()). This dropped

I noticed that in the narrow band and wide band destroy functions only the main pointer is being freed. I think that it should be: void nb_decoder_destroy(void *state) { DecState *st; st=(DecState*)state; speex_free (st->inBuf); speex_free (st->excBuf); speex_free (st->innov); speex_free (st->interp_qlpc); speex_free (st->qlsp); speex_free
