Description tim blechmann 2008-02-07 10:22:05 UTC 
gcc crashes with an ICE, when generating code with debugging information. if the flag -g is omitted, the code compiles fine ...

gcc is invoked like this:
gcc-4.2 -v  -save-temps -DNDEBUG -D_PTHREADS -D_THREAD_SAFE -D_REENTRANT -D_POSIX_SOURCE -march=i686 -O -Wfatal-errors -I../../Demo -I../../Source -g  -c ../../Demo/TestHashTable.cpp
Using built-in specs.

doesn't compile with trunk?

Comment 3 Joost VandeVondele 2013-03-29 11:09:49 UTC 
testcase doesn't compile with trunk anymore. I suspect the original problem is fixed. If not, please provide an updated testcase.
