segfault building gd2 on Mac OS Sequoia

[RivetBenoit (Benoit Rivet)]

Trying to install gd2 on Mac OS Sequoia on a mid 2012 Macbook Pro (using Open Core Legacy Patcher to install Mac OS Sequoia) fails due to segfault, as shown line 2148 on the attached log file.

:info:build clang: error: unable to execute command: Segmentation fault: 11
:info:build clang: error: clang frontend command failed due to signal (use -v to see invocation)

Lines 2163 to 2165 claim there is a crash backtrace file, but I could not find any on the location indicated in main.log.

:info:build clang: note: diagnostic msg: Crash backtrace is located in

:info:build clang: note: diagnostic msg: (choose the .crash file that corresponds to your crash)

Files attached : main.log, gd_filter-a6bcd3.c and gd_filter-a6bcd3.sh (see lines 2161 and 2162 of main.log).

I tried sudo port clean gd2 and sudo port -f selfupdate as mentionned in ​https://trac.macports.org/ticket/71015 before attempting a new install of gd2 but this did not solve the problem. Strangely enough, gd2 installed fine on a 2012 MacMini with Mac OS Sequoia.
