Summary: Clang incorrectly warns of undefined behavior with
printf specifier %#X
Product: clang
Version: unspecified
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
AssignedTo: [email protected]
ReportedBy: [email protected]

Attempting to compile the following line of code:
printf("%#X\n", 50);
results in a spurious warning:
foo.c:4:14: warning: flag '#' results in undefined behavior with 'X' conversion
specifier [-Wformat]
printf("%#X\n", 50);
~^~
This is incorrect. The '#' flag applies to 'X' just as well as it does to 'x'.
