Follow-up Comment #41:

I built with enabled address sanitizer flags and ran "make check". During the
fixed tests in publish/publish.tst, I got a heap-buffer-overflow.
I was able to reproduce reproduce it twice (out of two tests) when running the
complete test suite.

The attached log contains the backtrace and other info from the address
sanitizer.

I'm not sure if this is related or something different. But it might be a
graphics/threading issue afaict.

Wrt what Pantxo wrote on the maintainer's mailing list [1]: I came across this
blog post [2]. It looks like the general idea could be applied
cross-platform.
Would that be helpful?
