Bug#584327: python-rdflib: fails with SIGBUS on mipsel - breaks build of enigmail
severity 584327 wishlist tag 584327 + moreinfo thanks the bug report in its current form has little value. - recheck with gcc-4.5, gcc-snapshot - combine the object files of a build with -O0 and -O2 to find the file with the issue. - maybe reduce it further, find the reason about this SIGBUS, and if it's a compiler issue at all. -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".

clone 584327 -1 reassign -1 gcc-4.4 found -1 4.4.4-1 block 584327 by -1 thanks I think ideally the fix should be made in gcc, if it is a mipsel compilation problem. The first step is to reproduce it with the latest gcc upload... -- Tim Retout signature.asc Description: This is a digitally signed message part
Bug#584327: python-rdflib: fails with SIGBUS on mipsel
Hey again, The question about Qemu is in fact very silly, because I didn't realize it wasn't working in the build daemons as well. I'm sorry about the noise.

Bug#584327: python-rdflib: fails with SIGBUS on mipsel
Hey, Thanks for reporting. At the first glance, these are my (probably wrong) thoughts: As expected, it works well here (amd64, python2.6, rdflib 2.4.2-1+b1). Your debug steps are clear, but I'm not really sure if python-rdflib is the one to blame here. "Bus error" looks more like an internal Python interpreter malfunction than a problem in the library itself, maybe caused by porting issues. OTOH, given it fails calling query() (SPARQL query parsing is involved), the problem may be in the C extension (SPARQLParserc.so). As a starting point, I should investigate if SIGBUS is raised either by a problem in the extension or is Python-related. If you don't mind, I've a couple of questions for you. Perhaps this is a dumb question but, is Qemu MIPS emulation reliable enough to use it for debugging purposes? Have you tried it in real hardware? Does it fail anyway? Do you know about any other python library with C extensions experiencing the same behavior in your Qemu image? Or maybe crashing with other Python/OS/whatever internal errors? Thanks.
