How to use a fork emscripten version?

I did operations follow the docs, but my patch didn't work. The reason of I want use costum build because I found an exception.

#15 common::timer_manager_t::init()::$_0::__invoke(unsigned int, unsigned long)

callback  fail: Exception: out of bounds memory access

I use wasm-micro-runtime for runtime.

Then I add a printf in dlmalloc.c

void dlfree(void* mem) {
    /*
     Consolidate freed chunks with preceeding or succeeding bordering
     free chunks, if they exist, and then place in a bin.  Intermixed
     with special cases for top, dv, mmapped chunks, and usage errors.
     */

    if (mem != 0) {
        printf("222222222222222");
        printf("111111111111 dlfree ptr: 0x%p",mem);

but no output print How can I slove that?

Emscripten will auto-build libraries as it needs them, so if you modify dlmalloc.c and then delete libdlmalloc* (which will be in the cache dir) then next time you run emcc it will rebuilt it with your changes.
