GCC says ``` ../cpython/Parser/string_parser.c: In function ‘fstring_find_expr’: ../cpython/Parser/string_parser.c:404:93: warning: ‘cols’ may be used uninitialized in this function [-Wmaybe-uninitialized] 404 | p2->starting_col_offset = p->tok->first_lineno == p->tok->lineno ? t->col_offset + cols : cols; | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~ ../cpython/Parser/string_parser.c:384:16: note: ‘cols’ was declared here 384 | int lines, cols; | ^~~~ ../cpython/Parser/string_parser.c:403:45: warning: ‘lines’ may be used uninitialized in this function [-Wmaybe-uninitialized] 403 | p2->starting_lineno = t->lineno + lines - 1; | ~~~~~~~~~~~~~~~~~~^~~ ../cpython/Parser/string_parser.c:384:9: note: ‘lines’ was declared here 384 | int lines, cols; | ^~~~~ ``` and, indeed, if `PyBytes_AsString` somehow fails, lines & cols will not be initialized.
