I'm trying to debug Mozilla using Insight.
When I run mozilla with the debug option the insight debugger comes
up and lets me start mozilla. I click the run button and it starts
and then does a break at main. When I press continue mozilla comes
up but insight never responds again (not screen refresh or button
response.
It seems that gdb is sleeping in sigsuspend.
It appears that gdbtk-hooks.c:693 the code
turns on a timer
waits for the timer or a child thread to signal
turn off the time
From looking at the code it seems that this timer isn't actually set. I
changed the name of the new threads target, which means that it isn't
recognized by gdbtk.c:target_is_native() anymore, and Insight thinks
that it doesn't need the timer. Try adding "multi-thread" to the list
of native targets in gdbtk.c:target_is_native(). I'm pretty sure
that'll work.
