>This is the typical problem with array bounds checking in gcc

This has nothing to do with gcc. The style message is produced by cppcheck,
a static analysis checker.

> Unfortunately, gcc has roughly a one source line window for analysis

Suggest new code:

while (k < XrdSecPROTOIDSIZE && k < len && buf[k]) { k++; }

it is often a wise idea to look before you leap.
