Veli-Pekka,

Could you please get a stack trace for this? You can do that by running:

llvm-gcc -v -emit-llvm testi.h

That will produce a command line that llvm-gcc runs (probably cc1) to do the
actual work. Simply run that command under a debugger with the options printed
out by llvm-gcc and when it fails (segmentation fault), get a stack trace
(probably the "where" command). Please post the stack trace here.

Thanks,

Reid.

I cannot reproduce it here (mingw32, llvm-gcc 2.0cvs as of March). The result is
.gch file.

Veli-Pekka, have you used 1.9 sources/binaries or built llvm-gcc from svn?

Recent addendum of eraseLocalLLVMValues() breaks this again (However, release
branch is happy!)

Sorry, eraseLocalLLVMValues() wasn't commited yet. It seems to be local problem
of mine and Duncan's tree :)
