ggml_graph_compute: Assertion `false' failed

[muoten]

Examples work fine for me, but I get an error when trying different wavefiles larger than 21s:

./main -m models/ggml-base.en.bin mycut-22s-16khz.wav
whisper_model_load: loading model from 'models/ggml-base.en.bin'
[...]
main: processing 'mycut-22s-16khz.wav' (352000 samples, 22.0 sec), 2 threads, lang = en, task = transcribe, timestamps = 1 ...
[...]

main: ggml.c:6658: ggml_graph_compute: Assertion `false' failed.
Aborted (core dumped)

It's apparently fixed if I comment the assert and substitute by cgraph->work = NULL; in ggml.c. But I guess it's not the best workaround, as it crashes again with sigfault if audio duration is more than 43s aproximately.

Running on Ubuntu 18.04 LTS (GNU/Linux 4.15.0-187-generic x86_64), after fixing CACHE_LINE_SIZE and initializers issues #11

Any hint? Thanks!

Hi, I am pretty sure that the suggested initializer fix in #11 is wrong.
You have to use struct ggml_cgraph gf = {}:

struct ggml_cgraph gf = {}; gf.n_threads = n_threads;

I've already pushed this fix on master, so I think you can simply update to HEAD.

It works! Thank you very much!

Amazing work, btw. Kudos :)
