[Users] Seg fault in CCTKi_ScheduleCallFunction: strcmp of timer->schedule_bin

[Scott Hawley]

I'm running on NICS's nautilus, using the GNU compilers.   And I get a
segmentation fault at Line 2767:

while (timer && strcmp(timer->schedule_bin, data->schedule_bin))



"timer" acquires the (bad) address 0xfefefefefefefeff, and the strcmp is
still being executed, so it seg faults.

"attribute" seems to have a valid address, and so does attribute->timers
(0x55cb6cc0).  But attribute->timers->schedule_bin has a bad address.
("next" is NULL, btw.)

Does anyone have a suggestion?

Thanks,
Scott
What follows is my .par file
The seg fault happens AFTER it exits my thorn TexMEx, btw.
