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.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).
