--- Begin Message ---Package: flint Version: 2.5.2-8 Severity: importatnt Tags: sid, patch Justification: FTBFS User: debian-m...@lists.debian.org Usertags: mips-patch Flint-arb FTBFS on mips and arm with following error: > add_si....../Makefile.subdirs:84: recipe for target > '../build/arf/test/t-add_si_RUN' failed > make[2]: *** [../build/arf/test/t-add_si_RUN] Segmentation fault Full log is available here: https://buildd.debian.org/status/fetch.php?pkg=flint-arb&arch=mipsel&ver=2.8.1-2&stamp=1470100740 https://buildd.debian.org/status/fetch.php?pkg=flint-arb&arch=armel&ver=2.8.1-2&stamp=1470093777 This issue is related to count_leading_zeros implementation in longlong.h. If the same implementation is used for i386 and amd64 (instead of existing arch specific implementation), the same issue will appear. Reported issue with more details is available here: https://github.com/fredrik-johansson/arb/issues/150 Solution is to use clz builtins. I had proposed this solution to upstream and it was merged. https://github.com/wbhart/flint2/issues/283 Patch that contains needed changes is attached. If flit-arb is build against flit that is built with mentioned patch applied, all tests will pass. Could you consider including attached patch?
