* dc: execute shouldn't pop if stack head is not a stringBrian Foley2019-09-051-0/+10
| | | | | | | | | | | | | | This matches the behaviour of both GNU dc (as specified in its man page), and BSD dc (where stack_popstring() pops only if the head is a string.) Add a couple of tests to verify this behavior. function old new delta zxc_vm_process 6882 6884 +2 Signed-off-by: Brian Foley <bpfoley@google.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
