This is an out of bounds access caused by a broken curve type value in a map. In this case on ctf8, the 6th and 7th envelope have such a broken value (2752512 and 527 respectively), valid values are 1-5. I've heard that the old editor shouldn't get much attention anymore, but i think ctf8, being an official map, should be fixed. ``` Thread 1 "teeworlds" received signal SIGBUS, Bus error. 0x0000555555671a0c in CEditor::RenderEnvelopeEditor (this=0x555555935dd0, View=...) at src/game/edit...

Those values are not clamped: https://github.com/teeworlds/teeworlds/blob/ab384e4838fe808ccfebd0707f505e247eb50cb5/src/game/variables.h#L30-L31 This is particularly a problem when you put a negative value. They should be clamped between 1 and something sane, like 2000
