manojgupta added a comment. Hmm, looking deeper, gdb (actually binutils), is doing something weird.
https://github.com/bminor/binutils-gdb/blob/master/include/safe-ctype.h /* Prevent the users of safe-ctype.h from accidently using the routines from ctype.h. Initially, the approach was to produce an error when detecting that ctype.h has been included. But this was causing trouble as ctype.h might get indirectly included as a result of including another system header (for instance gnulib's stdint.h). So we include ctype.h here and then immediately redefine its macros. */ #include <ctype.h> #undef isalpha #define isalpha(c) do_not_use_isalpha_with_safe_ctype #undef isalnum #define isalnum(c) do_not_use_isalnum_with_safe_ctype <snip> So any use of isupper/islower etc will cause an error. Why this patch is triggering it: It adds an include of #include <__format/formatter_integral.h> which ends up including <locale> which has internal definitions of isupper/islower causing clang to complain. Any suggestions on what would be the right fix here?
