FTBFS in disco-proposed

[Olivier Tilloy]

LibreOffice 1:6.1.3-0ubuntu6 has been failing to build in disco-proposed on amd64 and arm64 for about a week.
The failure is a unit test that segfaults (CppunitTest_sw_odfexport).

I have reproduced the segmentation fault, I'm attaching a backtrace.

This looks vaguely similar to https://cgit.freedesktop.org/libreoffice/core/commit/?id=603074c5f2b84de8a24593faf807da784b040625, but the crash happens in libodfgen-0.1.so.1.

I went ahead and rebuilt the libodfgen packages (unmodified) on the machine where I can reproduce the crash, installed them, and now the crashing unit test passes.

I am now doing a full package build to confirm that rebuilding libodfgen would be sufficient.

If it is, that probably means there's an ABI change somewhere in the toolchain (maybe in gcc 8.2.0-10 ?).

Rebuild was successful. I'll upload a no-change rebuild for libodfgen.

Done, libodfgen 0.1.7-1ubuntu1 is in disco-proposed. I mistakenly used a "ubuntu1" suffix instead of "build1" to push a no-change rebuild, which means this will need a manual sync next time, sorry about that.

I triggered a rebuild of libreoffice for amd64 and arm64.

libreoffice 1:6.1.3-0ubuntu7 successfully built on all architectures in disco-proposed.
