Re: posix_spawn

[Kirill A. Korinsky]

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.

well... seems that Xcode 15 with macOS 13+ requires additional patches.

attached patch allows to pass configure but build failed at:

COMPILER>/bin/sh: line 1: 15229 Illegal instruction: 4 

at the attempt to run raw_pre_gcl. I'll try to investigate this (get the stacktrace) in next few days.

Here I've attached two patches:

1. add missed sizeof(char) which is used inside code, but never checked

2. add missed unistd.h which is nessesary to pass checking on xcode 15 on macOS 13
