Dear Gap Forum,

Problem: When DirectoryTemporary is called, more than 5000 calls to
Process with the output stream being a text stream results in an
error. (The error always occurs on exactly the 5000th call).

Version/Platform: GAP4, Version: 4r1 of 26-Jul-1999, on linux and solaris.

Example Code:

NumTimes := 0;
tmpfile := DirectoryTemporary();
Command := "/bin/date";

Test := function()
   local a, str;
   NumTimes := NumTimes + 1;
   str := ""; a := OutputTextString(str,false);
   Process( DirectoryCurrent(), Command, InputTextNone(), a, []);
   CloseStream(a);
end;

for i in [1..10000] do
    Test();
od;

Running this results in:

mafalda(101) gap < test.gap
GAP4, Version: 4r1 of 26-Jul-1999, i686-pc-linux-gnu-gcc

return ExecuteProcess( dir, prg, input![1], output![1], args );
EXECUTE_PROCESS_FILE_STREAM( dir, prg, input, new_output, args ) called from
Process( DirectoryCurrent( ), Command, InputTextNone( ), a, [ ]
); called from
Test( ); called from
<function>( <arguments> ) called from read-eval-loop
brk> NumTimes;
5000

Removing the call to DirectoryTemporary() causes the code to work
fine. Replacing the StringStream with OutputTextNone() also causes
the code to work fine.
