Hi im getting random exception 28 and exception 9 when doing a simple client.publish(), but only with 2.1.0-rc2, with 2.1.0-rc1 it doesn't fail.

perhaps @igrr would be interested in this issue too.

here are the crashes

this is my code

    loops++;
    DEBUG.println(); 
    DEBUG.print("loop: ");
    DEBUG.println(loops);
    char s_loops[10];
    sprintf(s_loops, "%d", loops);
    char ptopic[100];
    strcpy(ptopic, topic);
    strcat(ptopic,"loop");
    DEBUG.println("loop pub ready");
    client.publish(ptopic,s_loops);
    DEBUG.println("loop published");

when client.publish crashes, obviously it never gets to say "loop published"

Could you please try the same with git version of the core? I think i have fixed one issue with lwip which could lead to these crashes after rc2.

mtnbrit commented 8 years ago

It looks good so far, thanks @igrr.
