Hi everyone,

On one of my embedded Linux architectures I get a SIGTRAP when executing iocInit in softIocPVA.

This is the stack trace:
#0  0x0fdadd3c in typeinfo for epics::pvAccess::ChannelArray () from /usr/local/epics/base-7.0.3/lib/eldk42-

Any idea what's going on? It is running on a PPC CPU.
