Hi Dirk,
Ernest indicated that this might be resolved by patching the

that is possible then I am disinclined to create a workaround, but
if not

then I will see what can be done.

Hi
The bug also occurs with -O2, only -O1 is safe.

gcc 3.2.3 is the standard version on Scientific Linux 3, which we
still

have in use at the SLS. I would very much appreciate a workaround
in the

EPICS code.

Wouldn't a workaround be to just use -O1 for the file(s) where the
problem is occurring?

Changing source code to try to deal with compiler problems,
especially when the workaround is known, doesn't seem like a very
efficient use of resources. Even more so when the compiler in
question is getting rather old.
