I would also suggest that you provide as much detail as you can (e.g., complete code)
rather than snippets.

Hi Jim,

What does the code at the other end of the message queue look like? Does
it get called from interrupt context, or from task-level?

The problem might be that you can't use C++ code inside an ARM ISR (I
don't know whether that's true or not, but it's conceivable), and since
the libCom/osi/os/default/osdMessageQueue.cpp implementation is written
in C++ the problem is with the choice of using the epicsMessageQueue
inthe first place. As I said I don't know whether that is a restriction
but it's something you should check.
