Description of problem: There are four SIGSEGV messages visible in sagemath build log during building docs. Version-Release number of selected component (if applicable): sagemath-7.3-4.fc26 How reproducible: Always. Steps to Reproduce: 1. fedpkg clone rpms/sagemath && cd sagemath 2. fedpkg build --scratch --nowait --arch=x86_64 Actual results: [...] + /usr/bin/python2 -m docbuild --no-pdf-links -k all html Setting permissions of DOT_SAGE directory so only you can read and write it.

This probably occurred because a *compiled* module has a bug in it and is not properly wrapped with sig_on(), sig_off(). Python will now terminate. ------------------------------------------------------------------------ Expected results: No segfaults during build. Additional info: This is not new. Previous build logs show SIGSEGVs, too: https://kojipkgs.fedoraproject.org//packages/sagemath/7.3/3.fc25/data/logs/x86_64/build.log
These should be related to symmetrica. It is happening for some sagemath rpm package releases. Any help debugging it is welcome :)
