Test project
I'm getting a segfault while trying to compile some code with a precompiled
header.
This error does not append when trying to compile the file directly, so I
cannot attach a preprocessed version.
I didn't managed to narrow down the problem as much as I would like, but I
managed to get a way to reproduce it though.
I'm working on a Mac OS X 10.6.8 / x86_64.
To reproduce the error, you can try to compile the attached archive.
Uncompress the archive and 'cd' to the uncompressed directory.
Edit the compile.sh script to change clang path if needed.
run the script.
$tar -xzf crash.tgz
$cd crash
$./compile.sh
