When a program I created runs, it results in the following core dump.
This is inside an interrupt handling routine. Also, the DIO board
shares
an IRQ with a NIC. Is that the issue, or what is happening?

When a program I created runs, it results in the following core dump.
This is inside an interrupt handling routine.
Would you post the code of your interrupt handler. I suspect you are
calling
an illegal function (most C function cannot be used inside a ISR). Other
possibility is a bug in the code that creates a SIGSEGV. Could also be
a stack overflow, ISR uses the kernal STACK which is rather small.
Also, the DIO board
shares an IRQ with a NIC. Is that the issue, or what is happening?
It’s not an issue if the DIO board is PCI and if your handler behaves
properly. Your handler should check if the source of the interrupt
is the DIO board, if not if should exit and do nothing.

Mario:
I have posted the code in a new chain - sorry.
Look at the “Code changes…” thread.
