Description harry.kantor 2011-09-20 20:50:08 UTC 
Description of problem:

When attempting to compile cppunit tests, I receive a message:

g++: Internal error: Segmentation fault (program cc1plus)

The code I'm testing has worked before I placed a forward declaration in it.


Version-Release number of selected component (if applicable):
gcc-c++-4.1.2-51.el5.x86_64.rpmrp
cppunit-1.12.0-3.el5.rf


Additional info:
I have attached the core dump.

Created attachment 524092 [details]
Additional core dump

I've attached a core dump with the forward declaration removed.  The compiler is still crashing.
Comment 2 Jakub Jelinek 2011-10-21 12:22:09 UTC 
Coredump isn't useful for debugging compiler problems, we need a preprocessed source on which it can be reproduced.  By any chance, aren't you using PCH?
Comment 3 harry.kantor 2011-10-24 13:52:48 UTC 
Please cancel this issue.  There was a problem with my "depend" target, which caused one of the object files to not be rebuilt.

What is PCH?

Per c#3.
