in thread pack() returns an unusable string

Guessing is sometimes fine, but the OP gave an entire and complete test script which you can examine and even run. If I make a small modification to the test script given we can test the theory:

# use warnings; $template = 'd<'; $nv = 2.4; $p = pack $template, $nv; $s = "'$p'"; print ">$s<\n"; system $^X, '-wle', "print unpack('H*', $s);";


>'333333@'< 3333333333330340

running a 64 bit build of 5.32. Note that there is an ETX character between the final 3 and the @ character, which, when you think about it, is the string that the unpack is showing us so for the success case there is a trailing @ and it isn't swallowing the trailing '.
