Hi,
In check_backtrace_functions(), most accesses to the input string follow the pattern (*newval)[i]. However, the empty-string check is currently written as:
if (*newval[0] == '\0')
While functionally correct due to how the compiler handles the address-of-address context here, this form is semantically misleading. It relies on implicit operator precedence rather than explicit intent.
The attached patch rewrites it as:
if ((*newval)[0] == '\0')
This change ensures semantic clarity and maintains a consistent dereferencing style throughout the function. No functional changes are introduced.
