Aloha,

In the recent past the TCS IOC for CFHT switched EPICS
versions from 3.13.6 to 3.13.8. A CA client on an HPUX
host (which remained under 3.13.6) started crashing
with a core dump not much later. Running purify against
the client yielded several BSR (Beyond stack read errors)
from */epics/base/src/ca/access.c/iocinf.c
I compiled the client against 3.13.8 libraries and the
BSR error disappears.  This is good, however it is of
concern that an issue of compatibility between the versions
may be in question?

Here are a few preliminary results from purify (more running 
time needed of course for 'core' error to occur) 

Thoughts? 

regards & thx,
rosemary. 

------------------------------------------------------------
Client compiled with 3.13.8 libs - purify log - no errors
(see further below for client compiled with 3.13.6 libs & BSR errors)
