Subject: [PATCH v1] guc: make dereference style consistent in
 check_backtrace_functions

In check_backtrace_functions(), the empty-string check is currently
implemented as:

    if (*newval[0] == '\0')

while the rest of the function consistently accesses the string as

    (*newval)[i]

This patch rewrites the check as:

    if ((*newval)[0] == '\0')

This change ensures semantic clarity and maintains a consistent
dereferencing style throughout the function. No functional changes
are introduced.
