crash hooking functions without return value

[valerino]

hi,
have you tried to hook void functions ?
i.e. void AudioRecord::stop() into /system/lib/libmedia.so

it crashes after returning from the hook, or after a few calls. probably compiler optimizations on functions returning void.
seems your library works fine in any other case except this ....

regards,
valerio

Perhaps it's something in your hook. We'd need to see more of your code to know what's happening.
