hi. sorry about the delay.
i've done this but i'm not familiar with running programs
inside gdb and what i saw looked useless so i don't think i
did it correctly. it just contained the last function in the
trace before vim's signal handler takes over (as seen when
run outside of gdb) so it's probably just the signal handler
itself with no reference to the preceding stack. what did i
do wrong?
i've included the previously mentioned stack traces using a
lesstif that was configured with --enable-debug as well as
the useless trace from when running vim inside gdb. they
are at the end of this message.
it seems in both cases, it crashed at Primitive.c:1443
which makes me think that (*extptr)->widget_baseline,
while non-zero, might have been corrupted earlier?
using the core dumps, i printed all of the values mentioned
on the line of code where it crashed:
(gdb) up
#7 0x28130805 in XmWidgetGetBaselines (w=0x82403d8, baselines=0x77ace888,
line_count=0x77ace884)
at Primitive.c:1443
1443 return ((*extptr)->widget_baseline) (w, baselines,
line_count);
(gdb) print extptr
$1 = (XmPrimitiveClassExt *) 0x81c076c
(gdb) print *extptr
$2 = (XmPrimitiveClassExt) 0x823a6f8
(gdb) print (*extptr)->widget_baseline
$3 = (XmWidgetBaselineProc) 0x4741545f
(gdb) print w
$4 = (Widget) 0x82403d8
(gdb) print baselines
$5 = (Dimension **) 0x77ace888
(gdb) print line_count
$6 = (int *) 0x77ace884
(gdb) print *baselines
$7 = (Dimension *) 0x77ace8c8
(gdb) print **baselines
$8 = 59656
(gdb) print *line_count
$9 = 675194796
does any of this look wrong?
cheers,
