Package: jumpnbump Severity: important A raspbian user reported that jumpnbump "crashes while jumping", but only if sound was enabled. The issue was also reported by a ubuntu powerpc user. (back when ubuntu still supported traditional powerpc)
https://bugs.launchpad.net/ubuntu/+source/jumpnbump/+bug/722370 https://bugs.launchpad.net/raspbian/+bug/1639586 Neither of the original reporters tracked down this issue, but another raspbian user was able to track it down to a char signedness issue and has posted a fix upstream at https://gitlab.com/LibreGames/jumpnbump/-/merge_requests/33/diffs In the C standard, the signedness of type "char" is implementation defined. In practice it varies between architectures. on x86* it is signed, but on arm* and powerpc* it is unsigned. The result is that when dj_play_sfx is called with the "channel" parameter set to -1 on an architecture with unsigned char it instead gets interpreted as 255 resulting in an overflow. I have not personally tested this issue but I intend to do so soon. If I get no response to this bug and I get time to test out the patch I will likely upload a NMU in a week or so.
