-s EXPORT_NAME=... + pthreads breaks in Node.js

[RReverser]

Passing any custom -s EXPORT_NAME=... in combination with -pthread fails to execute the resulting code in Node.js:

rreverser@rreverser:~/emscripten$ ./emcc -pthread temp.c -o temp.js -s PTHREAD_POOL_SIZE=1 

rreverser@rreverser:~/emscripten$ node --experimental-wasm-threads --experimental-wasm-bulk-memory temp.js
Before Thread
Printing GeeksQuiz from Thread 
After Thread
main thread called exit: keepRuntimeAlive=true (counter=0)
program exited (with status: 0), but EXIT_RUNTIME is not set, so halting execution but not exiting the runtime or preventing further async execution (build with EXIT_RUNTIME=1, if you want a true shutdown)

rreverser@rreverser:~/emscripten$ ./emcc -pthread temp.c -o temp.js -s PTHREAD_POOL_SIZE=1 -s EXPORT_NAME=Smth

rreverser@rreverser:~/emscripten$ node --experimental-wasm-threads --experimental-wasm-bulk-memory temp.js
worker.js onmessage() captured an uncaught exception: ReferenceError: __filename is not defined
pthread sent an error! undefined:undefined: __filename is not defined
