Assertion base > stack_size / 2 failed located in the calculate_stealing_threshold function

[Alexufo]

version: 3.1.56, 3.1.60

Code without threads works fine, but on multithreads i got

wasm.js:3690 Assertion base > stack_size / 2 failed (located in the calculate_stealing_threshold function, line in file: 572)

And part in js from emscripten

I have a debug mode. In release mode, the error doesn't seem to occur

Do you know where calculate_stealing_threshold is defined so what its trying to do? It don't think its part of emscripten itself.

Does increasing the stack size help? I.e. does building with -sSTACK_SIZE=16mb make the problem go away?

calculate_stealing_threshold - from tbb lib

thank you. Yes it helped.

What is the danger of a large stack? Can it impose a restriction on something?
