Not work with different model

[msqr1]

I tried not to set ALLOW_MEMORY_GROWTH with pthread because I do lots of JS read and writes. See
https://emscripten.org/docs/porting/pthreads.html?#special-considerations

last section about pthread and allow memory growth

[korabelnikov]

@msqr1 I tried to rebuild using your make script, I've set 600mb instead of 300, but the error persists.

model, I used, from vosk-browser

https://github.com/ccoreilly/vosk-browser/raw/gh-pages/models/vosk-model-small-ru-0.4.tar.gz

[korabelnikov]

the execution steps after model creation but then I got error with pointer to std::string (I suppose)

[msqr1]

Without getting my hand dirty, I can't know what is going on. You can try with o0, g3 and assertions and sanitizers to debug, I'll try it later tonight. If you discover anything, please share it so I can improve this!

[korabelnikov]

good, idea, I'll try it right now

but pointer to the tar is correct, I compared memory view with offline hex viewer

[korabelnikov]

According to assmebly, it fails at std::string::substr, so I think, it's here

[korabelnikov]

I managed out, I repacked tarball given by vosk-browser (I removed top-level hidden file, and all the hidden files there).

[msqr1]

So the issue was that model files wasn't tgz'ed in the top-level directory, right?

[korabelnikov]

not exact, the issue was in that, you have a line in code which assume that all the files in tarball have '/' in their path, and then you cut the dirname out. But tarball from vosk-browser contains some hidden files at top level.
attempting to find '/' returns -1
then substr(path, -1, len(path))) crashes the program

[msqr1]

Alr imma fix this! Thanks for your help!

[msqr1]

@korabelnikov It took a long time, but it seemed that I fixed my code. Could you recheck so I can close the issue?
