jalex mentioned this on #perl. I'm not sure if he sent in a bug report or not.
This program:
#!/usr/bin/perl -w $x = "123 56"; $x =~ / /g; print "$x\, "\, pos($x)\, "\n"; { local $x } print "$x\, "\, pos($x)\, "\n";
produces the output
123 56\, 4 123 56\, Use of uninitialized value at test.plx line 5.
The search position for a match appears to be reset when the target variable goes through a 'local' save and restore.
I get the same results on 5.005_03 on linux.
