../include/internal/ethr_mutex.h:656: Fatal error in ethr_mutex_lock():
Invalid argument (22)
Aborted (core dumped)
This is an interesting one. Looks like a use after free perhaps?. Is it easy
to reproduce? Wonder if it is a resource reference counting bug: a destructor
is called, we are deallocating, then some thread tries to lock it. The error
comes from:
```
static ETHR_INLINE void
ETHR_INLINE_MTX_FUNC_NAME_(ethr_mutex_lock)(ethr_mutex *mtx)
{
int res = pthread_mutex_lock(&mtx->pt_mtx);
if (res != 0)
ETHR_FATAL_ERROR__(res);
}
```
