crash in clang::CodeGen::CodeGenPGO::getRegionCount #52991

Open omajid opened 2 years ago

omajid commented 2 years ago

On Fedora 35, building the .NET runtime (with profile guided optimizations enabled) leads to a crash:

git clone https://github.com/dotnet/runtime
cd runtime
./build.sh clr -c Release

This produces:
