Let me summarise how it crashed on Xcode 15 with macOS 14.

To test it I've used two gcl via MacPorts:
 - gcl which is 2.6.14
 - gcl-devel which is the last available commit at master 01ed2e0b2f540031171d2258ddccb951735827e7

gcl is build with patches:
 - dont-override-CC-or-MACOSX_DEPLOYMENT_TARGET.patch
 - fix-memory-corruption-on-macOS.patch
 - compatibility-with-xcode15.diff
 - Respect-provided-CFLAGS-to-compile-bin-dpp.diff
 - old-macOS.patch

gcl-devel is using:
 - draft-posix-spawn.diff
 - compatibility-with-xcode15.diff
 - Respect-provided-CFLAGS-to-compile-bin-dpp.diff

Crashes attached as gcl.txt and gcl-devel.txt

It crashes the same way on arm64 when I use rosetta to emulate x86_64 and on native x86_64.

To make things easy I've attached all used patches / stacktrace to this email.
