[RFA/commit] Internal error while loading core on alpha-tru64
Thu Dec 31 07:03:00 GMT 2009
There is an internal-error due to GDB not being able to find
the inferior address space when trying to load a core file on
The core file is for a program that does not use threads. The name
of the section where the registers is saved is .reg. core_open
prefers .reg/NN rather than .reg, and has some special code to
handle the case where no .reg/NN section was found.
/* Either we found no .reg/NN section, and hence we have a
non-threaded core (single-threaded, from gdb's perspective),
or for some reason add_to_thread_list couldn't determine
which was the "main" thread. The latter case shouldn't
usually happen, but we're dealing with input here, which can
always be broken in different ways. */
struct thread_info *thread = first_thread_of_process (-1);
if (thread == NULL)
inferior_ptid = pid_to_ptid (CORELOW_PID);
The problem is that the code above is it is using add_inferior_silent.
As a result, we end up with a second inferior in our list (which I do
not think is expected), and also this new inferior has no program or
The fix I applied was to replace the call to add_inferior_silent
by a call to inferior_appeared... I think that this was the right
thing to do.

Internal error while loading core on alpha-tru64.
* corelow.c (core_open): Delete unused local variables.
Use inferior_appeared instead of add_inferior_silent.
Tested on alpha-tru64 with the AdaCore gdb-testsuite (I can no longer
run the dejagnu testsuite on this platform). This is the only platform
where I observed this issue.
Will commit in a few days unless there are any objections.
