[Jed-users-l] bug in re_looking_at() ?

[Ulli Horlacher <framstag@xxxxxxxxxxxxxxxxxxxx>]

I have a slang function, which inserts "  " at the beginning of each line:

bob;
while (not(eobp)) {
  ifnot (re_looking_at("[ \*] ")) insert("  ");
  bol;
  down_1;
}

When the buffer has more than 2500 lines, I get a "Stack Overflow Error"
and in the traceback buffer I see:

/sw/ubuntu-10.04/jed-0.99-19/jed/lib/site.sl:1414:re_looking_at:Stack
Overflow Error
  Local variables for re_looking_at:
        String_Type re = "[ *] "
/sw/ubuntu-10.04/jed-0.99-19/jed/lib/select.sl:44:<top-level>:Stack Overflow Error
Traceback: evalfile
***string***:1:<top-level>:Stack Overflow Error
Traceback: called from eval: evalfile("select");

re_looking_at() seems to leave a value on the stack. 
When I modify my code to:

bob;
while (not(eobp)) {
  ifnot (re_looking_at("[ \*] ")) insert("  ");
  pop;
  bol;
  down_1;
}


everything works.

I assume this is a bug of re_looking_at() ?
