Is there any debugging output I can enable from DirectFB (especially the
matrox driver) which will help?
You could compile with --enable-trace which should give a backtrace
without gdb.
AFAICS the only place in maven_init() where it could segfault is
direct_memcpy(). But I don't think it's actually segfaulting there
because then the segfault should happen when calling DirectFBCreate().
I think maven_init() might be a red herring... I've rebuilt DirectFB
from source (not using a Gentoo ebuild) and it's crashing when calling
RGB_TO_YCBCR() in the second iteration of the loop in spicSetRegion().
Before the loop starts, palette is set to 0x20013f00, no idea if this is
a reasonable address though.
Got to go out now... I'll carry on digging later.
Regards,
James.
