search for: removekey

I get the error below (and have for a couple weeks now) when trying to build llvm-gcc on Ubuntu Feisty. In the meantime, on Ubuntu Gutsy, everything has been building fine. Both are release builds for x86. John cc1: StringMap.cpp:177: void llvm::StringMapImpl::RemoveKey(llvm::StringMapEntryBase*): Assertion `V == V2 && "Didn't find key?"' failed.

> I am having the same problem. It was "introduced" by revision 54811, > so it looks like a memory corruption problem. Investigating. Interesting. Bootstrapping with gcac works! Some tests with valgrind also work. My next try is to add some debug code to do bounds checking in SmallVector.

This looks like either an lli bug, or invalid bitcode (see my remark on the verifier above). If it passes the verifier, please reduce a testcase and open a bug report.

...-checking does not currently select the LLVM debug build to link into llvm-gcc, so you have to set this manually), I do not see the error, only the Release build. valgrind seems clean on the Release build.

Hi, When i wanted to build the llvm-gcc, i got the problem as following. ========================================================================================================================== cc1: /home/cllou/LLVM/llvm-2.4-dir/llvm-2.4/lib/Support/StringMap.cpp:177: void llvm::StringMapImpl::RemoveKey(llvm::StringMapEntryBase*): Assertion `V == V2 && "Didn't find key?"' failed. ../../llvm-gcc4.2-2.4.source/gcc/libgcc2.c:809: internal compiler error: Aborted Please submit a full bug report, with preprocessed source if appropriate.

This series of patches address several issues causing memory usage to grow indefinetely on a long lived process. These are not convenional leaks -- memory would have been freed when the LLVM context or/and JIT engine is destroyed -- but for as long as they aren't the memory is usage effectively ubounded. The issues were found using valgrind with '--show-reachable=yes' option: 1.
