Experimental Physics and
Industrial Control System

When I use an non-existent PV  via labCA in matlab, my matlab session dies.
e.g.
 > lcaGet ('garbage')
hangs for a minute or two, then takes down matlab.
Hitting control-c during the timeout also crashes matlab.

I'm running matlab 7 under linux.

I picked up what looked like the most recent
labCA (2.0 alpha).

Can  labCA be made to do anything other than hang and crash, like print a
'Channel connect timed out' error?

Problems of this kind usually occur due to improper C++ exception
handling, i.e., when the code that implements 'throwing' an exception
doesn't match exception handling.

If the workaround lined out in the ReleaseNotes doesn't work
for you, please check if a trivial mexFunction that
just calls mexErrMsgTxt("Testing error"); works fine or
if it crashes matlab. Then submit a detailed report (log, crash
dump etc.), please.

Thanks,
