Hi,

I have a task that calls pvload every time a semaphore is given from a
sub record subroutine. This scheme worked fine under epics 3.12.3, but
now that we upgraded to epics 3.13.4 the task is crashing and the
semaphore gets corrupted. The task code is the following:

int ecsSystemInitializeTask ()
{
  while (TRUE) {
    semTake(ecsInitSemId, WAIT_FOREVER);
    pvload ("./data/ecsInit.pv", "top=ec:", 2, 1);
  }
  return (0); /* should never get here */
}

If I remove the call to pvload in the task then the problem goes away.
Also, running pvload from the VxWorks shell as follows:

	pvload "./data/ecsInitCP.pv","top=ec:"

works fine all the time. Is there something that changed in the way
pvload is used in 3.13.4?

Thank you,
Pedro.
