Where does this new crash come from? Does it give you a better stack trace?
I tried hard, I cannot reoproduce this on on another computer. On the
problematic computer (Gentoo linux, x86/32, libart 2.3.21 gcc 4.9.2)
- no optimizations (-g -O0) to compile PRICE -> no crash
- -g -O1 or -O2, I get a useless trace:
Program received signal SIGSEGV, Segmentation fault.
0xbfffcb89 in ?? ()
(gdb) bt
#0 0xbfffcb89 in ?? ()
#1 0x00000000 in ?? ()
I think it is totally unrelated to GUI and BACK.
PRICE's PRWindowController gets a notification and has this line:
imgSize = [[[self document] activeImage] pixelSize];
this causes the crash. Supposing activeImage is nil, what pixelSize will
I get?
Accessing a method on a nil object? and if that method doesn't return an
object but a struct?
I know that on SPARC accessing members of a NULL struct causes problems,
but the above?
I substituted the code with this:
img = [[self document] activeImage];
imgSize = NSZeroSize;
if (img)
imgSize = [img pixelSize];
and it works fine. What do you think?
