Hi,
I'm trying to debug my X program. However, when I run it in gdb, I get a
SIGTRAP when stepping over XOpenDisplay(""). Continuing I get it another
time (sorry, not exactly sure where), continuing, my program runs fine
(except for the bugs that I introduce...).
Should this worry me?
I've downloaded cygwin an dXfree 1 week ago, so am running the latest of
everything.
