I checked the newest version and debugger is entered as it should.
Also (atan (complex 0.0d0 1.0d0)).  But I noticed significant
change: no traping mode seem to be the default.  Previously
apropriate condition was raised (as expected by FriCAS) now
I just get:

#C(#<DOUBLE-FLOAT quiet NaN> #.SI:DOUBLE-FLOAT-POSITIVE-INFINITY)

and need to pass '--trap-fpe' to ECL.  Worse, executable seem to
default to non-trapping mode and it is not clear how to make
them use trapping mode.
