Internal compiler error when building on AIX

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!
