Hinko,

Is the problem fully reproducable ?
Did you do a real "make clean" ?

Does "git bisect" help ?
Can you run under valgrind ?

Questions over questions..

Hi Mark,

I'm trying out the asyn4-30 with latest areaDetector code in GIT.
When clicking on the 'Erase/Start' on the Timeseries panel of ADCSimulation
Detector I'm getting a segfault from asyn code:

Does not happen with asyn4-27.
