I am getting a very weird, random crash in:
libsystem_kernel.dylib`__workq_kernreturn:
0x7fff8381de60: movl $0x2000170, êx
0x7fff8381de65: movq %rcx, %r10
0x7fff8381de68: syscall
0x7fff8381de6a: jae 0x7fff8381de74 ; __workq_kernreturn + 20
0x7fff8381de6c: movq %rax, %rdi
0x7fff8381de6f: jmp 0x7fff8381a175 ; cerror_nocancel
0x7fff8381de74: retq
0x7fff8381de75: nop
0x7fff8381de76: nop
0x7fff8381de77: nop
How can I track this down since it does not seem to be tied to anything
specific.
It does seem like if I remove a call to
NSData* imageData = [[self myImageRep]
representationUsingType:NSJPEGFileType properties:imageProperties];
It no longer crashes, but the crash happens 3-5 seconds after this call when
my program should be idle.
Thanks.... Never seen anything like this and have spent several hours trying
to track it down.
