Fuzzer is crashing when using latest zlib-ng 2.0.6

You can see the output of fuzzer here: https://github.com/Blosc/c-blosc2/runs/5833640686?check_suite_focus=true

Apparently this is only happening when starting to use zlib-ng 2.0.6. @nmoinvaz may you provide any hint?

I did some fixes in the ndlz code, but still having issues with one: https://github.com/Blosc/c-blosc2/runs/5848395013?check_suite_focus=true . @oscargm98 could you have a look at this one? You can still use the same branch that I am using, i.e. zlib-ng-2.0.6. Thanks.

I have started a new fix-fuzzer branch for fixing this. @oscargm98 please use the new one instead.

@oscargm98 I have just merged fix-fuzzer branch (via PR https://github.com/Blosc/c-blosc2/pull/391). But the issue mentioned above is still there, so help would be appreciated.

@FrancescAlted have you tried with the latest develop branch?

In the end that was fuzzer trying a new path, and not related with zlib-ng (fuzzer triggering when updating to the latest version of it was just a coincidence, I think). But thanks!
