Hello,

I have a problem using epicsTimerQueueActive.

When I create a time queue with epicsTimerQueueActive::allocate(true)

then release it with epicsTimerQueueActive::release() and after that

call epicsTimerQueueActive::allocate(true) again, I get a segmentation

fault due to access to address 0.

I see no crash if I do not call release().

Interestingly, I see this effect only on my armv5teb (aka xscale_be)

embedded Linux system, but not on x86 or on p2020 ppc (big endian, too).

All accesses are in the same thread (_main_) during device initialization.

This happens when I use StreamDevice with at least two records connected

to a non-existing asynOctet port.

Any ideas?

Dirk
