Whats at 0x0?! Are you winding me up, or is it some kind of offset?

What's at $pc (where PC is 0x4012e7e9 or 0x80850d5), symtab==0 indicates a symtab lookup failure.

See below. I can send the full transcript if necessary.

How much more?

...
infrun: TARGET_WAITKIND_STOPPED
infrun: stop_pc = 0x4012e7e9
infrun: random signal 20
infrun: resume (step=0, signal=20)
infrun: prepare_to_wait
infrun: infwait_normal_state
infrun: TARGET_WAITKIND_STOPPED
infrun: stop_pc = 0x4012e7e9
infrun: random signal 20
infrun: resume (step=0, signal=20)

infrun: prepare_to_wait
Breakpoint 3, Fsplit_window (window=137726961, size=137726961, horflag=137726961) at window.c:3688
3688 if (NILP (window))
(gdb) n

There appears to be stuff missing here, the output should contain something like:


	resume(step=1, signal=0)
	resume(step=0, signal=0)

as GDB single-steps the thread off breakpoint 3. The PC should be near or at 0x80850d5 found in the below.

infrun: infwait_normal_state
infrun: TARGET_WAITKIND_STOPPED
infrun: stop_pc = 0x4012e7e9
infrun: random signal 20
infrun: resume (step=0, signal=20)
infrun: prepare_to_wait
infrun: infwait_normal_state
infrun: TARGET_WAITKIND_STOPPED
infrun: stop_pc = 0x4012e7e9
infrun: random signal 20
infrun: resume (step=0, signal=20)
infrun: prepare_to_wait
infrun: infwait_normal_state
infrun: TARGET_WAITKIND_STOPPED
infrun: stop_pc = 0x80850d5
infrun: BPSTATE_WHAT_STOP_NOISY
infrun: stop_stepping

Breakpoint 1, internal_error (file=0x82214d7 "infrun.c", line=2671, string=0x81ef681 "%s: Assertion `%s' failed.") at utils.c:789
789 va_start (ap, string);
