--- Begin Message ---Source: pywavelets Version: 0.5.1-1.1 Severity: important User: debian-...@lists.debian.org Usertags: alignment Hi! I've been doing a full rebuild of the Debian archive, building all source packages targeting armel and armhf using arm64 hardware. We are planning in future to move all of our 32-bit armel/armhf builds to using arm64 machines, so this rebuild is to identify packages that might have problems with this configuration. A feature of the arm64 kernel is that it does *not* support fixing up code with broken alignment, so code that might have built and run OK on our older armel/armhf build machines due to kernel fixups will now fail. When building your package, I've found a bus error (aka alignment fault). The full log is online at https://www.einval.com/debian/arm/rebuild-logs/armel/FAIL/pywavelets_0.5.1-1.1_armel.log for reference I've done a quick bit of debugging to find the source of the bug. Here's a gdb stacktrace and variable printout to demonstrate the problem. (sid-armel)steve@maul:~/debian/build/pywavelets/pywavelets-0.5.1$ gdb /usr/bin/python2.7 core ...
