TLDR, bottom section of the log:

...

Additional info

This happens only while trying to embed data into the Node.js binary. This works:

npm init --yes
echo "Hello, world!" > index.js
npx asar pack . app.asar
echo "int main() {}" | gcc -x c -
npx postject ./a.out NODE_JS_CODE app.asar

This fails in https://github.com/postmanlabs/postject/blob/0035c074f43185546dd65a6bffcfe78ccc96382b/src/postject.cpp#L24.

After building with -sASSERTIONS, this is the readable part of the error:

Aborted(Cannot enlarge memory arrays to size 82239488 bytes (OOM). Either (1) compile with -sINITIAL_MEMORY=X with X higher than the current value 16777216, (2) compile with -sALLOW_MEMORY_GROWTH which allows increasing the size at runtime, or (3) if you want malloc to return NULL (0) instead of this abort, compile with -sABORTING_MALLOC=0)
