This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.35 running under perl v5.8.6.
-----------------------------------------------------------------
[Please enter your report here]
It looks like dynamic scoping of $digit is not working properly when
recursion is used.
Consider:
sub b {
print "B $1\n";
$_[0] =~ /(l+)/;
b("allllocate") if $_[0] eq "hello";
print "E $1\n";
}
b("hello");
This prints
B
B ll
E llll
E llll
while I would expect the last "E" to be "ll".
Dynamic scoping works fine when different block is entered:
sub c {
print "B $1\n";
$_[0] =~ /(l+)/;
print "E $1\n";
}
sub d {
print "B $1\n";
$_[0] =~ /(l+)/;
print "M $1\n";
c("allllocate");
print "E $1\n";
}
d("hello");
This produces
B
M ll
B ll
E llll
E ll
as expected.
This behavior was tested with 5.005_03, 5.6.2, 5.8.6, and 5.9.1.
