wxWidgets Debug builds apparently have some tricky technique to validate

the match between wxString::Format() or wxString::Printf() format strings
with passed arguments, but does this at runtime, not compile time.
Fix some mismatches.  size_t is a 64 bit type on x86_64 whereas int and
unsigned are 32 bit types.  On 32 bit machines they are all 32 bits so
this error is probably not triggered.
