} It doesn't seem to be happening with TRAPUSR1, though: compare
}
} TRAPUSR1() { integer i; i=4; print i is $i; }
} kill -USR1 $$
}
} with the same function as TRAPALRM with a non-zero timeout. Slightly odd.
I should have looked more closely at this before reporting it ...
If you look again at the stack trace I sent, you'll see that TMOUT is a
special case; the code looks like this:
int tmout;
dotrap(SIGALRM);
if ((tmout = getiparam("TMOUT")))
alarm(tmout); /* reset the alarm */
Outside of dotrap(), global allocation is in effect. Inside the trap
function itself, heap allocation is.
It looks like that's the only place where getiparam() is called in a
global allocation context, so maybe it'd be sufficient to put HEAPALLOC()
around that one call, rather than inside mathevall().
