It depends on what details you want. cyg_thread_self() will tell you
the current thread. However, be careful, it could of been an ISR/DSR
that caused the exception, not the thread. 

If you have a hardware exception, eg /0, sigfault etc, the info
parameter passed to the exception handler may be the saved
registers. This is architecture dependent. eg look at
packages/hal/arm/arch/current/src/hal_misc.c lines 136-158 and follow
the code patch though into your exception handler.
