It would be good if you could analyse this with gdb further.
I recommend to obtain a more recent copy of gdb (e.g. gdb
5.0), in particular one compiled for your system (the one
you have is compiled for Solaris 2.4). You can get get
binaries from sunfreeware.com (although they don't have gdb
5 for Solaris 7; you might want to try the 4.18 that they do
have).

The important thing is that you need to run the setup.py
under gdb. To do this, please invoke the setup.py line
manually. I.e. if the makefile invoke

ENV1=val1 ENV2=val2 python-command python-options arguments

you will need to perform the following commands

ENV1=val1
ENV2=val2
export ENV1 ENV2
gdb python-command
run python-options arguments

As a side point, what is the exact gcc version that you are
usingq (gcc -v)? If that also is not a gcc for Solaris 7, I
recommend to re-install the compiler, or use the system
compiler.
