I have a problem when I compiled Emscripten code with -s ASYNCIFY=1 and call an external library class.

_setjmpTable
Assertion failed: mappedGlobals.find(name) != mappedGlobals.end() ? true : (std::cerr << name.str << 'n', false), file C:emslavebuildslavewin-tagbuilderemsdkbinaryentag-1.38.29srcasm2wasm.h, line 1659

The problem is mentioned in emscripten github issue here

The problem is because of the

The asyncify pass moves some code out of main, and then it can't find
those local vars

as Emscripten author said

The problem happens when I call other class from external libraries ( .bc ) and compile with ASYNCIFY=1. However when I remove ASYNCIFY everything is alright.

I also found that If I add the code before

jmp_buf env;
if(!setjmp(env)) 

 longjmp(env,1);
 emscripten_sleep(1000);

The code can be compiled successfully but it crashes when I ran it on a browser

How to solve the problem since I have to use both ASYNCIFY and a class from external library?

c++ emscripten

I have the same problem when I use emscripten_wget(...) with -s ASYNCIFY=1.
I have to use emscripten_async_wget instead, it need not ASYNCIFY.

P.s. I use emscripten version 1.38.29.

use EMTERPRETIFY instead of ASYNCIFY

FLAGS += -s EMTERPRETIFY_FILE="data.binary"
FLAGS += -s EMTERPRETIFY=1
FLAGS += -s EMTERPRETIFY_ASYNC=1

instead
