I know that Perl version of the bug occurred on both my work computer
(Win2K) and home computer (WinXP) both using the lastest Cygwin DLL.  
The C code I sent, produced the bug on my work computer.  I'll try my
home computer this evening.  Is it possible that something in my
environment is the problem?

I'm not really interested in the Perl version of the bug.  I thought that
the test case which you forwarded demonstrated the problem.

I don't know what it would be, if so.

Btw, please don't use raw email addresses in the body of your messages
and please *attach* the cygcheck output.  Don't just include it inline
in your message.

I get the same can't-duplicate as Chris does, on 'uname -a'=

CYGWIN_NT-5.1 DFW5RB41 1.5.20s(0.153/4/2) 20060209 14:37:47 i686 Cygwin

I don't have any of this stuff in $CYGWIN, might be worth a try to ditch it:

"
CYGWIN = 'server ntsec forkchunk:32768'

Btw, I have a hyperthreaded machine running at 3.06G with 1G of RAM.  I
wouldn't expect that to make a difference in this case, though.  I can't see
how this could be a N-processor race-related bug.

Maybe this is the one bug that HT actually masks instead of reveals. ;-)

Jerry,

  I've cc'd the cygwin list on this reply since the difference
(Win2K vs. WinXP) may be significant.  I'm also running cygwin
under Win2K.  It may be that others who have not seen this
error are also running under XP as well.

It behaves the same for me no matter where I run it.  I even increased the
final sleep time in case the program was exiting before the bogus alarm
was tripped.

Chris, Gary, et al,

  I'm able to reproduce this on my machine, but only when I'm
running it under rxvt.  If I run it from cmd.exe or within a
standard cygwin bash shell, then it completes without the
'-- BOGUS ALARM --' warnings.

Thanks for the test case but I don't see any difference in operation
between cygwin and linux when I run it:

    % ./ualarm.unix
    First ualarm  - one shot
    Second ualarm - one shot
    Last ualarm   - repeats 3 times
    Clearing ualarm

I have encounted a bug in Cygwin whereby ualarm(0,0) is not clearing
previously set ualarms.  This first cropped up while using Perl, but I
was able to reproduce the bug with the following 'C' program.  The gist
is that ualarm() is used several times, and then a final ualarm(0,0) is
executed to clear them.  This is followed by a usleep().  The alarm
signal handler shows that 'bogus' alarms are going off during the
usleep().  Without the signal handler, the program would terminate
prematurely due to uncaught SIGALRM.

/*
 * Reproduces bug associated with ualarm
 *
 * Make using:  gcc -o ualarm_bug.exe ualarm_bug.c
 *
 * Typical output:
 *
 *        First ualarm  - one shot
 *        Second ualarm - one shot
 *        Last ualarm   - repeats 3 times
 *        Clearing ualarm
 *        Sleeping
 *        --- BOGUS ALARM ---
 *        --- BOGUS ALARM ---
 *        Done
 *

#include <unistd.h>

/* Increments a counter when alarm goes off */
int tick;

void
inc_tick(int signal)
{
    tick++;
}

/* Prints out a warning message when an alarm goes off */
void
bogus(int signal)
{
    printf("--- BOGUS ALARM ---\n");
}


int
main(int argc, char **argv)
{
    int counter;

    /* Set incrementing alarm handler */
    signal(SIGALRM, &inc_tick);

    printf("First ualarm  - one shot\n");
    tick = 0; ualarm(10000, 0); while (tick == 0) { counter++; };

    printf("Second ualarm - one shot\n");
    tick = 0; ualarm(10000, 0); while (tick == 0) { counter++; };

    printf("Last ualarm   - repeats 3 times\n");
    tick = 0; ualarm(10000, 10000); while (tick < 3) { counter++; };

    printf("Clearing ualarm\n");
    ualarm(0, 0);

    /* Set warning alarm handler */
    signal(SIGALRM, &bogus);

    printf("Sleeping\n");
    usleep(500000);

    printf("Done\n");
    exit(0);
}
