C source code
I just tried to compile the package nesc-1.3.2 with the latest 4.7
snapshot 20110521 on a Fedora Linux x86_64 box.
The compiler said
charset.c: In function 'cpp_interpret_charconst':
charset.c:1517:1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
In gdb, I get
Program received signal SIGSEGV, Segmentation fault.

I think it's a duplicate of pr 49087. It was fixed on May 22, and your version
is from the day before.
