From: Oliver Reiter <oliver.reiter <at> snapdragon.cc> To: bug-gnu-emacs <at> gnu.org Subject: 30.1; feature/igc: multiple crashes with pgtk_handle_selection_* Date: Sat, 17 May 2025 22:43:08 +0200
Dear all,
I have encountered multiple crashes on feature/igc with pgtk when
copying from Emacs to somewhere else. All crashes seem to involve some
form of 'pgtk_handle_selection_*' function (xbacktrace is always empty).
These crashes appear to be reproducible for me, if you need further
info.
Best,
Oliver

Is there any way we could change our code to avoid bumping into this problem? The bug exists in a relatively new version of GCC, so more users will hit it in the years to come. One way is to force the use of -fno-tree-sra (for the affected versions of GCC, if we can identify them), but is there maybe a less blunt instrument? > > Configured using: > > 'configure 'CFLAGS=-g3 -ggdb -O3 -mtune=native -march=native > > -fomit-frame-pointer' CPPFLAGS=-I/home/reitero/.local/lib/mps > > Using -fomit-frame-pointer will result in the compiler putting > references to GC-able objects in %rbp; since MPS usually uses setjmp to > spill the registers to the stack, and setjmp "scrambles" %rbp for > security reasons, that will result in references which are invisible to > MPS, which will cause other crashes. But configure.ac on the branch forces -fno-omit-frame-pointer. Is that not working for some reason?
