Hi Alen, looks like it's some sort of memcpy issue, perhaps a bounds
error. Unfortunately the most interesting parameters got optimized out
there so can't see exactly how it's failing.
if (!upsidedown)
for (i = 0; i < height; i++)
MEMCPY_WRAPPED(dst + i * dstStride, src + i * srcStride, width);
If you're comfortable coding C and compiling xorg-server, the next step
would be to add more debugging around this chunk of code to see what
variable is triggering the error. Not sure if this can be done in gdb
or if it'd need to write to a log. valgrind might help too.
@Eddie, unless you can prove it is exactly the same crash (i.e.
identical backtrace), I would rather treat this as an -nvidia bug.
-nvidia replaces a huge amount of the X core with its own stuff, and
more often than not causes weird random issues.
