I get something like this :

==============
1.    /Users/manu/Documents/Sources/MacLibPc/H/Std/../Sdl/System.h:357:2:
current parser token ';'
2.    /Users/manu/Documents/Sources/MacLibPc/H/Std/../Sdl/System.h:267:1:

Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)

Thread model: posix
clang: note: diagnostic msg: PLEASE submit a bug report to

clang: error: unable to execute command: Segmentation fault: 11
clang: note: diagnostic msg: Error generating preprocessed source(s).
Command
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
failed with exit code 254
==============

when I tried to compile a source file through a symlink, and/or if its header
file is accessed through a symlink.
When the header is in accessed through a symlink, the crash report starts at :
"clang: error: unable to execute command: Segmentation fault: 11" (ie: no line
error reported)

The symlink is created with the following command :
ln -s /Users/manu/Documents/Sources/MacLibPc/
/Users/manu/Documents/Sources/SymLibPc
