Hi, Alan. Thanks for the feedback.
Found out that I'm still get DEBUGASSERT(pholder != NULL) in function nxsem_allocholder in file semaphore/sem_holder.c after DEBUGASSERT(sem->semcount<SEM_VALUE_MAX) fix, so it seems that they are not related. I'm trying to investigate this. пт, 3 июл. 2020 г. в 15:47, Alan Carvalho de Assis <acas...@gmail.com>: > Hi Oleg, > > I just responded your issue. > > I hope to have shed some light there. > > BR, > > Alan > > On 7/3/20, Oleg Evseev <ev.m...@gmail.com> wrote: > > Regarding to can driver, from some moment I started getting > > DEBUGASSERT(sem->semcount<SEM_VALUE_MAX) > > in sem_post.c.
