I'm fairly stuck on this one. Tried running old versions of packages on Sid
and can't reproduce the crash. I also build apache2 and libgnutls30 from
upstream sources and the crash still occurs on Zesty. Disabled apparmor,
and compared lots of build logs between Debian and Ubuntu to see if there
are any differences. I don't see any Debian patches in key dependencies
that would explain the ability to build.
At this point I'm starting to wonder if it's the toolchain or something in
the kernel. Perhaps there's a simpler explanation?
