openQA testing shows that anaconda consistently crashes when running against gnutls 3.7.5. The crash seems to be actually in Python itself, and an error message `free(): invalid next size (fast)` is shown. I don't have a full backtrace yet (this is slightly inconvenient to get for anaconda Python crashes). I suspect this is the same as upstream https://gitlab.com/gnutls/gnutls/-/issues/1367 - I'll try and fix Jeremy comes up with there. We have untagged gnutls-3.7.5-1.fc37 from Rawhide for now to avoid this breaking composes.

Within the release 3.7.5 we started using custom gmp memory allocator functions in order to increase the security level by nullifying memory. However, we did not realize that our gnutls_realloc_zero function was already broken (could cause heap corruption) and setting it as reallocfunc for gmp might have broken stuff. This upstream MR should fix this issue https://gitlab.com/gnutls/gnutls/-/merge_requests/1592
