Subject: [Ada] Add missing guard in __gnat_adjust_context_for_raise

This makes sure the pattern matching code in __gnat_adjust_context_for_raise
doesn't dereference a NULL pointer in case things go awry.

Tested on x86_64-pc-linux-gnu, committed on trunk

2009-11-30  Eric Botcazou  <ebotcazou@adacore.com>

	* init.c (__gnat_adjust_context_for_raise, Linux version): Add guard
	for null PC saved in the context.
