Re: Problem with catching exceptions on ARM

[David Chisnall]

Hi Mathias,

Can you try using a very recent trunk clang?  Support for ARM EABI exceptions 
has been present in clang for a while, but it was only enabled by default a few 
days ago.  Without the unwind tables, the runtime will abort when you try to 
throw an exception because it can't work out how to unwind the stack.
