SIGBUS in gx_engine::NeuralAmp::compute #190

Open edwloef opened 1 month ago

This occurs when changing the buffer size at samplerates other than 48000, with the NAM plugin loaded. Can't tell whether this is another pipewire-jack bug though, since the stacktrace isn't very helpful: bt.txt

gdb claims this to be the line it crashes at, which doesn't make much sense to me either: https://github.com/brummer10/guitarix/blob/be6310d565df7d34bb06ba08a69c44393c91c7d4/trunk/src/gx_head/engine/gx_internal_plugins.cpp#L1923

In the git version, it crashes somewhere in here: https://github.com/brummer10/guitarix/blob/9013250487851fb98bb936c9ca5d210cfb560ef0/trunk/src/gx_head/engine/gx_internal_plugins.cpp#L1925-L1928 maybe the difference is just down to debug symbols

Does that mean that it didn't crash under pipewire when you change the buffersize any more, without a neural model is running? Which version of pipewire do you use?

edwloef commented 1 month ago

Yes, the old crash no longer occurs since pipewire-jack 1.2.6, this commit fixed it: https://gitlab.freedesktop.org/pipewire/pipewire/-/commit/27961630a669f0a58ccbfe044cd0c3ebecbe77c0

Ah, that's nice to hear. Well, I just did some quick tests under jack and can't reproduce the crash under jack. As I'm still on pipewire 1.2.0 I can't test on pipewire, but, as it works flawless under jack I suspect pipewire to be the culprit.
