Description Charalampos Stratakis 2023-05-31 15:33:33 UTC 
Trying to build python3.7 on rawhide currently fails on i686 with the latest gdb. Last successful build was with gdb-12.1-10.fc38. Not sure on which version the issue appeared as koschei doesn't built for i686. It might not even be a gdb issue but filling the bug against it for more info.

The error message:

A fatal error internal to GDB has been detected, further
debugging is not possible.  GDB will now terminate.
This is a bug, please report it.  For instructions, see:

Comment 2 Kevin Buettner 2023-06-03 20:21:50 UTC 
FWIW, there was a recent soname bump for librpm - that's probably the reason for the librpm warnings.

Any thoughts about how I might reproduce this crash outside of the build environment?

I'm also curious about why python3.7 is being built...

Python 3.7 is being rebuilt to fix the high severity CVE-2023-24329

test_gdb works only on source builds so in order to reproduce it you'll have to clone the repository and test it out in a mock environment.

Within mock:
$ dnf builddep python3
$ git clone https://github.com/python/cpython.git
$ ./configure && make && ./python -m test -vv test_gdb

Interestingly enough I managed to reproduce it also on the main branch of CPython on 64 bits mock and also I've managed to fix it by doing a $ dnf debuginfo-install glibc libxcrypt.

However. I noticed that test_gdb is skipped on PGO builds from Python3.8 and onward: https://bugs.python.org/issue37023

On Python3.6 we skip test_gdb entirely. So I believe the proper course of action would be to skip test_gdb for python3.7's build.
