Hello Julien, > https://buildd.debian.org/status/fetch.php?pkg=giac&arch=amd64&ver=1.6.0.25%2Bdfsg1-2%2Bb1&stamp=1604135053&raw=0 To clarify, it seems it works on mipsel but not on mips64el ? It seems only 64bit architecture are affected ? > The failing test on amd64 is a segfault.

This is a fatal error. The test cannot pass. Probably PARI 2.13 needs a bit more memory than PARI 2.11. 512000 is still a very low value. We never test PARI with less than 8MB on 64bit system. 64bit systems use a bit more memory than 32bit system, so it is possible that 512000 is sufficient on 32bit but not on 64bit. The segfault is incidental. It is probably caused by giac not recovering properly from such fatal errors. Do you have a backtrace of the segfault ? Cheers, Bill
