[Pkg-openssl-devel] Bug#1110254: libssl3: segfault in libcrypto.so.3

[Stefan Ehmann]

I have noticed a similar issue in calibre:

$ unzip /usr/share/calibre/builtin_recipes.zip
$ ebook-convert bbc_fast.recipe out.mobi

ebook-convert usually crashes (or hangs) for me after 2-3 tries, e.g.,
malloc(): unsorted double linked list corrupted
Aborted

It sounds similar to <https://github.com/python/cpython/issues/136881>.

If I revert
<https://github.com/openssl/openssl/commit/340383f5f49f84ed802dac268e6c12971d837f75>
(and also 7141330fb98ceab643729f2d0f445f79f26addce), ebook-convert works 
fine again.

According to the comments, this is a bug in python. It is fixed in 
python 3.13, but there won't be an upstream backport to older versions.
