I'm having some trouble getting crash logs to symbolicate via xcode, and need
to investigate that further. Manually grabbing symbols using atos reveals the
method where it is happening, but I am unable to pinpoint the line number. The
crash happens at a very obscure point in program application, and lack of debug
support for LLVM binaries means it's quite hard to provide a sample
application.

I'll investigate some more and see if I can provide further information. Please
inform me if you have any tips.

I'm not sure if this is related to MT at all, but when running
'symbolicatecrash', it ends up running:

atos -arch armv6 -o 'osum/bin/iPhone/Release/osum.app/osum' 0x0005647c
0x004ccf98 0x00521804 0x00002fb0 0x003f4960 0x0026aa84 0x00509990 0x003bd7a0
0x0005002c 0x004a5778 0x000b31dc 0x000ad5f8 0x000ad2cc 0x00527bac 0x004f1b20
0x004a27bc 0x003b0780 0x004fff2c 0x00439934 0x004a47d4 0x00082588 0x000a38dc
0x000b166c 0x0028a144 0x00361c3c 0x000ad2ec 0x00509a24 0x001295b4 0x004cd08c
0x000b2f08 0x000a3928 0x003d0054 0x003f6978 0x003cf770 0x003d0604 0x003b5ff4
0x003b1f50 0x000a41a4

This doesn't successfully symbolicate, but if I manually run this command
pointing to the dSYM contents, it works correctly.

atos -arch armv6 -o
'osum/bin/iPhone/Release/osum.app.dSYM/Contents/Resources/DWARF/osum'
0x0005647c 0x004ccf98 0x00521804 0x00002fb0 0x003f4960 0x0026aa84 0x00509990
0x003bd7a0 0x0005002c 0x004a5778 0x000b31dc 0x000ad5f8 0x000ad2cc 0x00527bac
0x004f1b20 0x004a27bc 0x003b0780 0x004fff2c 0x00439934 0x004a47d4 0x00082588
0x000a38dc 0x000b166c 0x0028a144 0x00361c3c 0x000ad2ec 0x00509a24 0x001295b4
0x004cd08c 0x000b2f08 0x000a3928 0x003d0054 0x003f6978 0x003cf770 0x003d0604
0x003b5ff4 0x003b1f50 0x000a41a4

This may be due to something I'm doing incorrectly, and would appreciate any
thoughts on this matter.
