tests fail

[mouse07410]

Either the warnings are too pedantic/restrictive, or the sources are bad:

$ cd v4Tests
$ make

@usr3-1415 can you check this please?

Thanks for reporting this issue.
I locally ran the test case 01-INTEGER/007.asn1, which passed successfully. However, upon examining the generated source code, I identified a redundant local variable, which was declared and later incremented in a loop but had no effect on execution. I've removed this variable in a recent commit, which should resolve any related warnings or errors.

It's worth noting that you're likely using a more recent version of GCC that detects such issues, whereas the asn1scc Dockerfile specifies an older GCC version. This discrepancy explains why our GitHub Actions build-and-test pipeline hasn't encountered these errors, as it utilizes the environment defined in the Dockerfile.

As a result, similar issues may arise due to differences in compiler versions. We do plan to update the Dockerfile to use a more recent GCC version, but this may take some time as it requires verifying and addressing any new warnings or errors introduced by the update.
