You aren't using non pfmalloced data for attributes of the geoset, are you?
Make sure your fluxing is such that you don't increase the num prims before
you have valid vertex data for them.

Subject: A problem using fluxed geosets
My program has a bug in it that I was hoping someone could give me some
tips on tracking it down. I am using a fluxed geoset to dynamically
manipulate geometry while running. The program works fine for a while,
then crashes suddenly. On my Onyx2 it gives me the following message:
WARNING: /hw/module/1/slot/n1/node/cpubus/0/a: UCE interrupt on PIO
access
NOTICE: /hw/module/1/slot/n1/node/cpubus/0/a: User Data Bus error in
IO space at physical address 0xec10004 (EPC 0xda5d790)
[ESP System Information Notification]:WARNING:
/hw/module/1/slot/n1/node/cpubus/0/a: UCE interrupt on PIO access
[ESP System Information Notification]:NOTICE:
/hw/module/1/slot/n1/node/cpubus/0/a: User Data Bus error in IO space
at physical address 0xec10004 (EPC 0xda5d790)
On my Octane2, it just plain crashes the whole computer, requiring a
reset.
I used cvd to check out the core file, and found this call stack:
int pass_word_word_word(<stripped>) ["kon_vertarray.c":80,
0x0da5d790]
int __glkonDrawArraysNCTV(<stripped>) ["kon_gvertarray.c":208,

["tunnel.c":83, 0x100729a8]
int __start(<stripped>) ["crt1text.s":177, 0x100475f8]
I suppose the bug is just a bad pointer, but I can't find it. I was
hoping someone could give me a hint on where to look.
Thanks for the help.
