Fair enough :)

Here is the gdb output:

(gdb) run

Starting program: /Users/adinapoli/Library/Haskell/ghc-7.6.2/bin/threadscope

Reading symbols for shared libraries ++++++++++++++++++....................................................................................................................................................................... done

Reading symbols for shared libraries . done

Program received signal EXC_BAD_ACCESS, Could not access memory.

Reason: KERN_INVALID_ADDRESS at address: 0x0000000000000000

0x0000000000000000 in ?? ()

I have two hypothesis:

a) could be the RAM (tips about some RAM testing tool?)

b) could be some programs which is writing in that portion of memory, see:

Yes, can you show us a backtrace from gdb, and also look in your CrashReports
log folder to see if it gives a bit more information on the state of the
process at the time it died?

Thanks,
