x86_64-w64-mingw32-g++ -Wformat handling misparses the std::size_t
format string, causing a spurious error.
common/main/valptridx.tcc: In function 'void untyped_index_mismatch_exception::prepare_report(const char*, unsigned int, const void*, long int, const void*, const void*, char (&)[229], std::size_t)':
common/main/valptridx.tcc:36:182: error: format '%u' expects argument of type 'unsigned int', but argument 7 has type 'std::size_t {aka long long unsigned int}' [-Werror=format=]
This occurs even though the processed text uses %I64u (which is correct
for a `long long unsigned int`), not %u as shown in the error message.
static void prepare_report(const char *const filename, const unsigned lineno, const void *const array_base, const long supplied_index, const void *const expected_pointer, const void *const actual_pointer, char (&buf)[report_buffer_size], const std::size_t array_size)
{
snprintf(buf, sizeof(buf), "%s:%u: " "pointer/index mismatch:" " base=%p size=%" "I64u" " index=%li expected=%p actual=%p", filename, lineno, array_base, array_size, supplied_index, expected_pointer, actual_pointer);
}
In practice, all such sizes will fit in `unsigned int` because they are
the dimension of an array of large structures. Switch all platforms to
use `unsigned long`, which works everywhere and is at least as big as
`unsigned int`. Using `unsigned long` produces the same size as
`std::size_t` on all platforms other than Win64, where `unsigned long`
is only 32 bits due to the strange LLP64 model Microsoft picked.
