[Bug 1892558] [NEW] [SRU] binhex always segfaults

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Sudip Mukherjee (sudipmuk):

[ Impact ]

some of the binaries provided by macutils are completely unusable as they will immediately segfault as soon as they are executed.
The impacted binaries are:
binhex
tomac
frommac

This is because the relevant header file was not included and so as as
result the compiler assumed the functions return an integer.

[ Test Plan ]

1. Install macutils
2. Execute all the binaries provided by macutils for a basic sanity test

binhex -H
frommac -H
hexbin -H
macsave -H
macstream -H
macunpack -H
tomac -H

If the package is not fixed then binhex, tomac and frommac will result in segfault.
 

[ Where problems could occur ]

There is no change in code, only the relevant header file has been
included. And, so there are minimum chances of a regression. The change
has been part of Debian and also Jammy onwards and there has been no
regression reported.

[ Other Info ]

The testplan only does a basic sanity test. Ideally a macutils user
should test and confirm that everything is working as expected.

[ Original Bug Description ]

Steps to reproduce:

binhex -H

Expected result: binhex prints help information

Actual result: binhex crashes with SIGSEGV

Comments: binhex doesn't only crash with the -H flag, it crashes with
any flag. It appears to crash in the main() function before any argument
handling actually happens.

Version is 2.0b3-16build1.
