[ICE][Builtin] gccjit aborts with ICE when getting __builtin_alloca_with_align

[Schrodinger ZHU Yifan]

Hi,


The following code will trigger ICE:


#include <libgccjit++.h>
int main () {
        auto ctx = gccjit::context::acquire();
        auto func = ctx.get_builtin_function("__builtin_alloca_with_align");
        ctx.release();
}


Command line:

g++ test.cc  -lgccjit -o test && ./test



Error message:

internal compiler error: in make_type, at jit/jit-builtins.cc:4460x7d7f7372e1cd __libc_start_call_main
        ../sysdeps/nptl/libc_start_call_main.h:58
0x7d7f7372e289 __libc_start_main_impl
        ../csu/libc-start.c:36
