Hi Peregrine,

The vxWorks tShell crashes after calls to both malloc() and

iocInit within a st.cmd have been traced to the drvTS.c TSinit()
routine that is called within iocInit. The environment is
Power PC; VxWorks 5.4; EPICS R3.13.5 and requires definition

of local synchronized timestamp support routines

(http://www.aps.anl.gov/asd/controls/hideos/GTS.html).
This is a consequence of insufficient (none!) range checking for
access within the TSdata.event_table array of struct timespec

allocated in TSinit(). The quick patch is to always have an

ErSyncEvent() function that returns an event number less than

the return value of ErHaveReceiver() when supplying local
timestamp support. The harder correction is to rewrite drvTS!

....which is underway. I hope to fix some other problems, too.
The progress has not been as fast as I had hoped (busy with other

things) but the first rewrites (that can be published) should be ready
within a month or two.
best regards,
			Timo
