@Fabien-Chouteau We need to change in gcc.anod:

                    "https://github.com/iains/gcc-13-branch/archive/refs/"
                    + "tags/gcc-13.2-darwin-r0.tar.gz"

to

                    "https://github.com/iains/gcc-14-branch/archive/refs/"
                    + "tags/gcc-14.1-darwin-r0.tar.gz"

Following suggestions here, I've tried using later versions of Xcode (v1, v3; for v3, which doesn't provide m4, I've set M4=gm4); no change.

I've also tried removing the GCC configure setting --without-build-config, remembering vaguely a related issue (I had --with-build-config=no). No improvement.

The really strange thing is that this error happens in stage 2, where the compiler in use is the compiler built in stage 1 (i.e. a GCC 14.1 compiler). When I used my local GCC 14.1 to build a program with trampolines, it generated calls to ___gcc_nested_func_ptr_created and performed a static link, picking up the symbol from the new libheapt_w.a.

Using GCC 13.2, the same program with trampolines picks up ___builtin_nested_func_ptr_created from libgcc.a.

Running on Github, the built stage 2 gen_il-main

• fails to run, looking for ___builtin_nested_func_ptr_created
• which is the equivalent symbol generated by GCC 13.2
• in libgcc_s.dylib
• and is unsurprisingly missing from the version created by GCC 14.1.

but

• if it needs that symbol, how did it link?
• how come it needs that symbol anyway?
• and why is it looking for a shared library?
