Re: [Haskell-cafe] Threadscope 0.2.2 goes in segmentation fault on Mac Os X 10.8.3

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 Reading symbols for shared libraries . done Reading symbols for shared libraries . done Reading symbols for shared libraries . done Program received signal EXC_BAD_ACCESS, Could not access memory.

I know it's a bit difficult to debug this way, I can try debugging with gdb if it can help.

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?
