Backtrace of the crash
Hi,
I'm trying to compile the latest version of llvm. I have checked out the
release_40 branch in my worktree, but llvm-tblgen keeps crashing.
I am using debian testing with GCC 6.2.1
To reproduce the crash:
cmake -DLLVM_TARGETS_TO_BUILD=X86 -DBUILD_SHARED_LIBS=ON
-DCMAKE_INSTALL_PREFIX=$HOME/.local -DCMAKE_BUILD_TYPE=RelWithDebInfo -G Ninja
..
ninja lib/Target/X86/X86GenRegisterInfo.inc # to go straight to the crash
...
0. Program arguments: /home/philippe/packages/llvm/build/bin/llvm-tblgen
-gen-register-info -I /home/philippe/packages/llvm/lib/Target/X86 -I
/home/philippe/packages/llvm/include -I /home/philippe/packages/llvm/lib/Target
/home/philippe/packages/llvm/lib/Target/X86/X86.td -o
/home/philippe/packages/llvm/build/lib/Target/X86/X86GenRegisterInfo.inc.tmp
Segmentation fault (core dumped)
I am attaching the full backtrace
The crash does not occur when building in debug.</pre>
