Hi, I uploaded a new giac to unstable ; this package was building ok everywhere when it was last uploaded (a long time ago, september 2018), but now fails on s390x.
It's a scientific computation package, and the build process consists in essentially three steps : - build the source ; - build the documentation, running the executables from the previous step to show off their use ; - run the checks, by running the executables from the first step on stranger inputs, stressing the corner cases. The buildd managed went through the first two steps, but only a few tests ran, and already with a few failures (already a problem), until one of them had to be killed after a while, presumably because it was stuck (complete story here: https://buildd.debian.org/status/fetch.php?pkg=giac&arch=s390x&ver=1.5.0.85%2Bdfsg1-1&stamp=1579706992&raw=0 ). I wanted to work on it and get meaningful data for upstream, so turned to zelenka, the porterbox for this architecture. I followed the tutorial here https://dsa.debian.org/doc/schroot/ - as I'm already used to do when I get problems with other packages. But this time, the documentation step already fails : *** bug in PARI/GP (Segmentation Fault), please report. (repeated quite a few times before the compilation dies) I don't understand why I get so wildly different outcomes with the same source package : did something get into unstable and break things between the time the buildd ran and the time I tried to reproduce the issue ? Do you have any advice ? Thanks, JP
