Links OK with -O1, but crashes in asm2wasm with -O2 or -O3

[yksoft1]

Here is my build command line.
emcc -O3 -s USE_SDL=2 -s TOTAL_MEMORY=104857600 -s EMTERPRETIFY=1 -s EMTERPRETIFY_ASYNC=1 -s EMTERPRETIFY_WHITELIST=@d3.txt dosbox-x.bc --memory-init-file 0 -o dosbox-x.html
It crashes with such output.

If I replace -O3 with -O1, it worked but would still crash asm2wasm with -O2. Did I trigger a bug in binaryen? asm2wasm didn't use very large amount of memory before it's crashing.

Here are the files mentioned in the command line.

Thanks for reporting @yksoft1, turns out this was a missing case in binaryen. Fix is in WebAssembly/binaryen#1681 . I think we didn't notice it before because it only happens if the JS optimizer is run on very specific code (the JS optimizer runs here due to emterpretify).

I tried your branch asm2wasm-mod-sign, and it worked for linking my Dosbox-X fork now. Thanks!
