Problem with Freetype port with 6.0.9

[stuartjamesmcnicholas]

I have a problem with use of -fwasm-exceptions and Freetype port with version 6.0.9. Earlier versions do not exhibit the problem.

Many apologies if I am doing something wrong/unsupported, or if this is a duplicate.

Version of emscripten/emsdk:
MacOS

$ emcc -v
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 6.0.9 (4e4223852a0835923411059a3929907d7df1232e)
clang version 24.0.0git (https:/github.com/llvm/llvm-project 510126255f89d693717c1ce7105b593f995f07c1)

Souce code causing failure:

$ cat simple.c 
#include <ft2build.h>

int main(int argc, char *argv[]){
    return 0;
}
