From: Gregor Zattler <telegraph <at> gmx.net> To: bug-gnu-emacs <at> gnu.org Subject: 31.0.50; scratch/igc: segfaults on startup when called under gdb Date: Thu, 12 Dec 2024 15:26:32 +0100
Dear Emacs developers, this bug is not
relevant to my everyday usage of Emacs,
so please disregard if the report is not
helpful / appropriate at the time.
I try to use scratch/igc with my
standard Emacs runtime configuration
which includes running under gdb. On
the way Emacs crashes (see below).
I can start Emacs like:
~/src/emacs-igc2/src$ ./emacs --debug-init --eval "(setq load-suffixes '(\".el\"))" --eval '(setq load-prefer-newer nil)'
this is how I collected the infos for
this very bug report. Therefore the
standard bug report infos are from this
invocation without gdb.
Below the standard bug report infos
you'll see a gdb backtrace. There are
17 occurrences of "optimized out" values.
This I do not understand since I tried
to configure the building process as
debugging friendly as possible. Hints
as how to improve this are very welcome.
There is no xbacktrace, because
scratch/igc does not provide this.
I will try to keep the gdb session open,
but this is a laptop, which I use as
daily driver...
HTH and thabks for Emacs, Gregor
