I am experiencing an unusual run-time error on a relatively simple
program I wrote using Lattice C 5.04.
At the end of my program, I get a Software Error-task held window
followed by various Guru messages :
#00000003.00C39620 -- Address Error (usually)
#00000004.00C39E38 -- Illegal Instruction (occassionally)
#0000000B.00C39628 -- Opcode 111 (once)
My code resides between 00C70CCC - 00C718D2, so these addresses
are outside the code itself. My program does not use any Amiga
specific routines. It currently just uses stdio to and from the
shell window.
I added the following debug statement at the end of main and it does
get printed:
main()
{
...
printf("reached the end of the program\n");
}
I even tried putting an exit(1) statement as the last statement in
main, but it still gurus. There aren't even any files being
accessed !
I realize this isn't much to go on but does anybody have any ideas ?
Note : the program conists of just one source file and one header
file compiled and linked as follows -- lc -Lm file.c.
Please email to ewing@se-sd.sandiego.ncr.com.
Thanks,
Dave Ewing

You have runaway code. >My code resides between 00C70CCC - 00C718D2, so these addresses >are outside the code itself. The address given in the GURU number is that of the TCB (task control block), not the address on which the error occurred. >I added the following debug statement at the end of main and it does >get printed: That's real nice, but without the entire source code, it is impossible to determine what is happening. Try commenting out source code until the problem disappears. You may thus locate the problem. Then post the minimal source code which repeats the bug on Usenet. You'll get better answers.

Thanks to all who responded about my mysterious runtime error in Lattice C 5.04 (guruing at end of execution). The majority of responders suggested it was a stray pointer or array reference, however it turned out to be a stack overflow problem (thanks, John Meissen). Dave Ewing ewing@se-sd.sandiego.ncr.com
