Subject: crasher in dwarf2loc.c
Date: Wed, 23 Apr 2003 00:50:00 -0000 [thread overview]
Message-ID: <3EA5E370.F069D062@redhat.com> (raw)
Hey Daniel,
I've got a core dump coming from dwarf_expr_frame_base.
First you call get_frame_function, and then you immediately
use its return value. But get_frame_function can return zero,
so I think you need to check for zero before using it.
Michael
PS: more details: get_frame_block returns zero, because
frame_address_in_block returns a pc that is not in any block.
The crash occurs while running recurse.exp, when we have a
watchpoint on a local variable in an inner frame, and we
continue -- so I don't know the exact context; but I'm
willing to bet that it is trying to evaluate the local
variable after the stack frame has been destroyed.
