O' munificent maintainers of merry melt!
Thanks for suggesting a break point.
If I understand correctly, I did as you asked.
$ gdb
(gdb) file kdenlive
(gdb) b mlt_pool.c:142
(gdb) r
Thread 28 "RenderThread" hit Breakpoint 1, pool_fetch (self=0x809c8920)
at mlt_pool.c:142
(gdb) print self->size
$1 = 33554432
I expect you're in a better position to know
a.) if I did it right and
b.) whether 33554432 looks OK.
If you happen to have the time, and are so
inclined, I'd be interested in any further
thoughts you may have.
Thanks,
Kingsley
PS: The full back trace is attached.
