Hi all,
I’m picking development of an app that uses libsdl. There are various
issues, and I need to get a debugger on them asap. I tend to use ddd as I’m
not really that au-fait with gdb from the command line.
However, one issue that makes it difficult to use the graphical debugger is
that when I run the app with SDL_RESIZABLE instead of SDL_FULLSCREEN, any
attempt to e.g. minimise or move the app window, or cause it to lose focus,
results in a segfault.

I just wanted to confirm that I’m not doing anything silly - this is
supported by libsdl, right? Using libsdl 1.2.11, xorg 7.1 on Debian Etch.
I even tried looking at SDL_PumpEvents - I can’t see that this even calls
X11-KeyToUnicode, and nor that X11-KeyToUnicode calls getenv. I’d really
appreciate a clue, and I can provide more info if you tell me what you need.
