Jazz Jackrabbit 1 - level switch segmentation fault on OpenBSD about openjazz HOT 4 CLOSED

Instead of the above segfault, some test runs lead to the game being killed with the following on the console. This also happens on level change/load:

fishtank$ openjazz
pthread_mutex_destroy on mutex with waiters!
X Error of failed request:  BadShmSeg (invalid shared segment parameter)
  Major opcode of failed request:  130 (MIT-SHM)
  Minor opcode of failed request:  3 (X_ShmPutImage)
  Segment id in failed request:  0x2c0000f
  Serial number of failed request:  7133
  Current serial number in output stream:  7136

Yesterday I tested the following:

1. Changing the screen into a global to rule out the variable going out of scope - still crashing
2. Avoided calling SDL_Flip if either canvas or screen ->refcount dropped to 0 - still crashing
3. Avoided calling SDL_Flip if either canvas or screen ->pixels was null (0x0) - still crashing

I'm stuck and will need some pointers in further diagnosing this crash.

I reached out to Ryan C. Gordon on twitter while initially hitting my head against this crash. His reply (note he only saw the backtrace by then, I only just linked him this ticket).

I'm not sure; does this only fail on OpenBSD? Likely either a wrong surface size or a bogus palette, it's dying in the loop where it converts from paletted values to RGBA.

Since OJ is now ported to SDL2 and it only happened on OpenBSD so far, I am closing this without solution.
