lorder reports errors; for example, from mktemp

[Mark Rudolph]

If you run the lorder script from package bsdmainutils (version 11.1.2ubuntu1) on Ubuntu 18.04.1 LTS it reports several errors:

$ lorder a.o b.o
mktemp: too few X's in template ‘_reference_’
mktemp: too few X's in template ‘_symbol_’
a.o a.o
b.o b.o
sed: couldn't open file : No such file or directory
expr: Invalid character class name
/usr/bin/lorder: 80: [: -ne: unexpected operator
sort: option requires an argument -- 'o'
Try 'sort --help' for more information.
sort: option requires an argument -- 'o'
Try 'sort --help' for more information.
join: missing operand after '2.1'
Try 'join --help' for more information.

It seems the new script invokes mktemp with an invalid template.

I expected the program not to generate errors; they did not occur on Ubuntu 14.04.5 LTS (package version 9.0.5ubuntu1).

Status changed to 'Confirmed' because the bug affects multiple users.

This is due to a difference in the way GNU and BSD versions handle the -t argument. The BSD version assumes that it can add XXX if it likes to.

See both man pages. The BSD version calls the argument a prefix, which the GNU version 'a single file name component'.

Explains it even better.
