Summary: Core dump with newly built Python
Initial Comment:
This is on what started as a Red Hat 6.0 box currently
running a 2.4.19-pre9-ac3 kernel:
# gdb ./python ./core
GNU gdb 4.17.0.11 with Linux support
...
This GDB was configured as "i386-redhat-linux"...
Core was generated by `./python -E ./setup.py build'.

Turns out that the bad compile was the first sign of memory
starting to fail. Swapped in other memory and Python built
well. Sorry to trouble you all on this.

I'm really grasping here, but here are some more things to try:
Use python -S to start (since that's all that works):
Try each of these lines (if one crashes, restart and try a
different one):
import os
import site
# the following 3 lines need to be done in order
x = [1, 2, 3]
x[1] = 5
del x[1]
If you paste these lines into a .gdbinit file (or into gdb),
you can find out where in the python source the program
crashes:
define ppystack
while $pc < Py_Main || $pc > Py_GetArgcArgv
if $pc > eval_frame && $pc < PyEval_EvalCodeEx
set $__fn = PyString_AsString(co->co_filename)
set $__n = PyString_AsString(co->co_name)
printf "%s (%d): %s\n", $__fn, f->f_lineno,
$__n
end
up-silently 1
end
select-frame 0
end
then in gdb, type ppystack. That may provide more info.
Good luck.

Deleting .pyc files does not help.

One thing to try is deleting .pyc files. I don't think that'll help,
but it might...

Compiler: gcc version 2.95.3 20010315 (release) (built from tar)
Clean build: pretty much, but see closed bug 535545 (using a
slightly modified configure file courtesy of Martin v.
Loewis)
Other packages: yes many, no problems
"python -S": yes, a prompt!
Do anything?: I don't really speak Python - something you
can suggest?
Other versions: Yes, 1.5.2 (same compiler); also 2.2.1rc
(forget which), which built fine after correcting
configure's error noted in bug 535545 - whereas this version
dumped core at the step of the make process quoted above
(/python -E ./setup.py build)

What compiler & version are you using?
Did you start from a clean build?
Have you used the compiler for other packages?
If you start python -S, does that get a prompt?
If so, can you do anything?
Have you successfully built any other versions of Python on
this machine?
