This isn't too useful, unfortunately. The line numbers are an artifact
of the fact that there is no STABS information in the generated asm in
'sigfe.s'. Can you get an assembly listing of the lines around this
instruction?

I fixed a problem like this a while ago. It's difficult to see how this
case could occur unless you are using an old version of sigproc.cc, in
particular, the no_signals_available macro sounds like it isn't
up-to-date.
