Re: [PD-dev] pd external memory weirdness

Hi Tim, list,

First, I never wrote anything with pthreads, so this may be way off the mark, but this looks suspicious:

tim redfern wrote:

void thread_bang(t_thread *x) { char* temp=(char*)malloc(1000000); free(temp);

    pthread_t stest;
    pthread_create (&stest,&gen_attr,threadtester,(void *) x);
    post("hello world!");

}

stest disappears when the thread_bang() returns, the thread is still running, and maybe pthread internals write to stest after it is no longer there, which would be very bad: at best, a segmentation fault, at worst, no crash but wrong behaviour.

At a guess: malloc() a list node with the pthread_t in it, and store those nodes in a list in the Pd object struct.
