The previous version does not accept changes and is compiled by default without the NDEBUG option.

I'm not sure this is a good idea unless we can somehow convince the world to switch to use your fork and not the upstream one...

...oh i see there's no upstream one?

Should we try to convince Linux distributions to switch to your repository?

Before proposing the PR I made the same reasoning as you. But then I thought: what is kimageformats on oss fuzz for? My answer: To solve the security problems of plugins in kimageformats.

With this PR I hope to close all those issues on OSS-Fuzz that get stuck on assert. And at the same time have a slightly more reliable version of the library. Better than doing nothing. Don't you think?

We deactivated the plugin in kimageformats because the library is practically abandonware (but it is still present in all distros) so we don't have to convince anyone to use a fork :)

I suggest trying the library here with our plugin and see how things evolve.

ok fair enough.

Admins please merge this.
