C programming/debugging mailing list?

[zen at freedbms.net (Zenaan Harkness)]

The detox program doesn't work quite right, so I'm trying to learn C to
fix it, and part of the code looks like a bug to me.

Any recommendations for appropriate mailing list to post questions?

E.g. debian-devel or perhaps something lower volume?

( This particular example:
 
 repo: https://anonscm.debian.org/cgit/collab-maint/detox.git
 
 file: src/clean_string.c
 
 line: from 545:
    if (new_value == -1) {
       continue;
    }
 
 This is dealing with malformed unicode chars in UTF-8, and I'm pretty
 sure the above should actually be:
    if (new_value == -1) {
       input_walk++;
       continue;
    }
 
 otherwise, if the method actually gets a malformed UTF-8 encoded unicode
 character, it looks like it will loop endlessly.
 
 The bug I'm looking for is a different bug again...
)

Thanks in advance,
Z
