Error message instead of discontigous warning

Windows 32 Bit, SWI-prolog 8.1.15

Dear programmers,

I start SWIPL, then File/New… and then I type the following little program:

% :- discontiguous a/0.

a.
b.
a.

Then I try to compile with Ctrl-C Ctrl-B. I get the error

ERROR: c:/users/matthias/documents/prolog/123.pl:5:
ERROR: format/3: Type error: text' expected, found ansi(code,’~p’,[a/0])’ (a compound)

I can make the error disappear by uncommenting the first line with the “discontiguous”. In any case, I think the compiler should not raise an error, but a warning that the a/0 are not placed next to each other in the code.

Thank you for your consideration.

Best wishes,

Matthias

Seems a Windows specific issue. I’m traveling without access to Windows :slight_smile:

For what it’s worth, the problem does not appear on a 32-bit linux build either. Therefore, indeed, it is windows-specific.

Best wishes,
