Re: [Bug-apl] SVN 595

[Fausto Saporito]

Just another bit of information:

this code is never executed (from Workspace.cc), I got before this the
floating point exception error.

  COUT << "DUMPED WORKSPACE '" << wname << "'" << endl
        << " TO FILE '" << filename << "'" << endl
        << " (" << function_count << " FUNCTIONS, " << variable_count
        << " VARIABLES)" << endl;

regards,
Fausto
