Hi Mark,
The problem happened more than one year ago that there were
really some confusions among multiple issues. I had to change
the "transform" record to "dfanout" one only because the application
would suffer if the "stopAllMotor" database is loaded. Back then, I was
reserved in reporting this because my application went through other
debugging, too. Once the system ran smoothly, I had to switch to another
higher priority project that I completely forgot about the history when this
issue was probed.....
For the record, yesterday, I had a chance to access the system to verify the
"transform" record. It turns out that the system runs fine even if the
transform record is used. Thus, I think you can use the transform record
as you wish.
Cheers,
Kate

Actually I use Linux, Windows and Cygwin IOCs in addition to vxWorks. I have never had a problem with the transform record on any of these platforms, and others report no problems on RTEMS. I agree that the dfanout can be used instead of the transform in this particular application, but there are many applications where this is not true, the transform record provides unique capabilities.
Thus, if you are convinced that you have found a bug in the transform record it would be most helpful if you could track it down. Of course it is possible that the bug is elsewhere in your application and the use of the transform record just happens to expose it.

Can you figure out why the transform record is causing the crash? It is widely used with no other problems that I know of.
You use vxWorks. We use RTEMS.
A generic record such as "dfanout" works very well for the purpose.
In fact, I do not think a custom record such as a "transform" record is
needed.

Subject: stop all motors
Hi,
If the "all_com_32.db" is loaded in the database, it triggered system
crash while we were running one of our RTEMS applications.
I traced down that the bugs were caused by the "transform" record
(e.g. transformRecord.c) for the motor "allstop" function. However,
a generic record "dfanout" can replace it to function correctly.
The attached all_com_32.db is what I used to solve the problem.
It seems to work so far.
Regards,
Kate
