[ID 19991110.001] study and //g bug?
Message ID:
199911101159.LAA10874@cassf.ast.cam.ac.uk
This is a bug report for perl from pak@ast.cam.ac.uk,
generated with the help of perlbug 1.26 running under perl 5.00502.
-----------------------------------------------------------------
[Please enter your report here]
If I run the following Perl program:
$field="disk whi";
study $field;
print "Studied!\n";
print "Found ",++$i, " matches\n" while($field=~/disk/g);
it gets stuck in an infinite loop, whereas if I comment out the
study $field line, it works fine and just returns one match.
[Please do not change anything below this line]
