[LLVMdev] [NVPTX] Strange assertion around BlockToChain.clear(); in Release+Asserts build
Hi, After building out project in release mode, caught an assertion, which we have not seen before: hello_f: /tmp/rpmbuild_debug/BUILD/llvm/build/include/llvm/ADT/DenseMap.h:126: void llvm::DenseMap<KeyT, ValueT, KeyInfoT>::clear() [with KeyT llvm::MachineBasicBlock*, ValueT = <unnamed>::BlockChain*, KeyInfoT llvm::DenseMapInfo<llvm::MachineBasicBlock*>]: Assertion `NumEntries == 0 && "Node count imbalance!"' failed.

[LLVMdev] [NVPTX] Strange assertion around BlockToChain.clear(); in Release+Asserts build
Dear NVPTX community, I've create a bug http://llvm.org/bugs/show_bug.cgi?id=13521 with reprocase for this issue. Please, help us to fix it. Last 1,5 months we regularly encounter & workaround or fix 1-2 bugs per week in NVPTX backend. This is definitely not the amount of work we can completely serve ourselves... We would really really appreciate some collaboration. Thanks, - D. 2012/8/3 Dmitry N.

[LLVMdev] [NVPTX] Strange assertion around BlockToChain.clear(); in Release+Asserts build
Unfortunately, I cannot reproduce this. Based on your bugzilla comment, it does look like a mis-compile with your system compiler. Does the same issue occur if you build LLVM as static libraries?
