Crash - XInitThreads has not been called

[Lexus89]

When i run the tool inside an Ubuntu VM (VMware Workstation) it crashes and displays the following error:

[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
macgeiger: ../../src/xcb_io.c:274: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.
Aborted

It runs for a few seconds and then stops.

UPDATE:

When running a few times more i also get this:

XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
      after 116 requests (116 known processed) with 2 events remaining.

yeah, i have the same issue when i use the SDL backend. it looks like its some bug in SDL 1.x which is triggered when several threads are active.

IIRC it first happened after this change 4554102

the only known workaround at this time is to either revert to before that commit or use the NCURSES terminal backend.

Thanks, with NCURSES all is working fine. Great tool!

meanwhile i developed a patch to fix this issue, see sabotage-linux/sabotage@261c526

since SDL 1.2 development has officially been halted, there's little chance this will ever make it upstream though.

i'll leave this open as the issue ain't really fixed until this goes into SDL itself.
