Perhaps you have a runaway pointer in your code which is overwriting some other part of memory and that causes problems later on.
Can you send your entire driver so we can have a look? If it's lengthy, please send it to me rather than to the entire list.

Hi

I've started experimenting with asyn.

Now I've created the routines for a driver with Common and devInt32
interfaces.

When I connected my own record (ai) 2 this to read it works fine.

Then I tried connecting a asynRecord to this.
It starts up fine.

But when I run medm to see this record the IOC segfaults.

location: base/src/db/dbLock.c line 242 : plockSet =
plockRecord->plockSet
because plockSet = null
and this is because precord->lst = null
And that must be the lockRecord or something.

I don't understand, the stack trace doesn't even run through asyn or my
own code.

I have no idea where to look for the fault :(
