#81 Segfaults for invalid arguments like "-name=value" instead of "-name value"

[Ryuichi Yamamoto]

x2x +sf data.raw  | frame -l 512 -p=80 > /dev/null

This will give a segmentation fault:

zsh: broken pipe                       x2x +sf data.raw | 
zsh: segmentation fault (core dumped)  frame -l 512 -p=80 > /dev/null

though I know the following works as expected:

x2x +sf data.raw  | frame -l 512 -p 80 > /dev/null

I think the CLI programs should show an error message instead of segfaults when users specify invalid argument(s).

FYI:

Thank you for using SPTK and kindly reporting the bugs.
We will check them.

Thank you for your kindly reporting. The segmentation error was caused by the poor command line option parsing. It is not easy to quickly solve the problem because all the SPTK commands include the same problem and the command line option parsing should be quite improved to prevent the kind of error.
We will fix it on the next major update.

I understand it requires quite a few efforts to fix. I hope you or someone else could work on this, or maybe I can help.

SPTK4 solved the problem.
