We could fix the website at least, if we had access permissions to that
server.

GNU Sather 1.3-beta-7 from gnu.org. I have tried compiling the compiler t
self with gcc 3.2, 3.2.1 and 2.96, but results are all the same.

The following program:

class MAIN is
   main is
      #OUT + "Hello World " + 3.str + "\n";
   end;
end;

When I compile it, I get the following warning:

Headers, compiling C... Regenerated 34 of 34 files...
flistFSTR312276997.c:548:15: warning: pasting "infinity" and "(" does not
give a valid preprocessing token
(77 seconds)

When I run the resulting program, the output is as follows:

signal 11 caught ...
Hello World Aborted

The sigsegv is, as seen above, caught before the message is written. GDB
notices it and says:

Program received signal SIGSEGV, Segmentation fault.
