Hi Paul,In debian/tests/decoding-test-data, please run "./gentestavi.sh". This command generates the test data (test_raw.avi).
And run "make". It will compile the test program (test1). Then run "gdb ./test1". In gdb prompt, execute "set args test_raw.avi". And then "run".When the bus error happened, execute "bt -full" and it will print out the backtrace.
You might want to install the debug symbols (-dbg) packages to get the symbol resolved.

Hi Paul,I need some help. Actually I know this bug for a while but I just cannot fix it. I've tried to reproduce the bug on qemu-user-static armhf chroot envorionment and PorterBox (abel.debian.org), on both platform the autopkgtest just passed without problem.I think the bug should be easy to locate if I can run gdb and see the backtrace when the bus error happened. But I just cannot reproduce this bug on my side or on porter box. If possible I hope to get some core dump when bus error happened on the machine that runs the test.Yours, Paul Paul Gevers 於 2022/4/1 03:31 寫道:Source: avifile Version: 1:0.7.48~20090503.ds-23 Severity: serious User: debian...@lists.debian.org Usertags: regression Dear maintainer(s),With a recent upload of avifile the autopkgtest of avifile fails in testing on armhf when that autopkgtest is run with the binary packages of avifile from unstable. It passes when run with only packages from testing. In tabular form:pass fail avifile from testing 1:0.7.48~20090503.ds-23 all others from testing from testing I copied some of the output at the bottom of this report.Currently this regression is blocking the migration to testing [1].
