For me, it crashes only on HP-UX and on Solaris. It crashes when 
generating the API files.

I have searched for it and just found the bug. In sipgen/transform.c in 
addDefaultCopyCtor() starting at line 1043 a structure for a default 
public copy ctor is allocated and initialized, but 
copyct->pysig.args[0].name gets never initialized. This causes the crash 
later in sipgen/export.c in apiArgument() at line 298 (The line numbers 
are based on snapshot-20061117).
