Hi,
I'm trying to build GPC (using the sources gpc-20050331.tar.bz2 and gcc-core-3.4.4.tar.bz2) on AIX 5.3. After working for a while the compiler crashes with an "Internal compiler error" (see below). Did anyone succeed building GPC on AIX using the recent sources?
Thanks for your help! Marcus

gpc-20050331 is more than year old and has a number of problems on non-Intel machines. The above does not look like one of the known problems (in fact the error message comes from C part of the compiler). However, I would first start with newer version. The latest snapshot is:

He succesfully build the compiler, but due to spurious warnings is unable to get meaningfull results from the testsuite (the problem is still under investigation).
