I'm working on it. I see it on ia64, so the root cause may be
an ia64-specific bug. The sig 11 happens when csh calls
sigsuspend:
(gdb) l *$b0
0x20000000000483a0 is in pjwait (/nfs/freebsd/base/head/bin/csh/../../
contrib/tcsh/sh.proc.c:513).
508 while ((fp = (fp->p_friends)) != pp);
509 if ((jobflags & PRUNNING) == 0)
510 break;
511 jobdebug_xprintf(("%d starting to sigsuspend for SIGCHLD on %d\n",
512 getpid(), fp->p_procid));
513 sigsuspend(&pause_mask);
514 }
515 cleanup_until(&oset);
516 jobdebug_xprintf(("%d returned from sigsuspend loop\n", getpid
()));
517 #ifdef BSDJOBS
(gdb)
