Hello, does anyone have a tip on how to work around the "Maximum call stack
size exceeded" error when running a UBsan-sanitized Emscripten program
under Node?
The error is:
"RangeError: Maximum call stack size exceeded
at _emscripten_return_address (a.out.js:6788:35)
at __ubsan_handle_dynamic_type_cache_miss (wasm-function[8220]:0x210eb3)

I'm not 100% sure, but it seems that the error doesn't indicate a bug in
the program, because it doesn't appear when compiling a small program
(e.g., a Googletest binary with 0 tests) and begins to appear even after
adding unused code (e.g., a bunch of disabled Googletest tests).
I tried passing "--stack_size=8192" to Node, but this didn't help; also,
when increasing the number (e.g., to 131072) I'm starting to get a
different error:
RuntimeError: memory access out of bounds
