Module Name: src Committed By: rin Date: Mon May 29 03:56:52 UTC 2023
Modified Files: src/sys/lib/libsa: subr_prf.c Log Message: libsa/printf: Do not fetch long va_arg as long long. This does real harm iff all of the following conditions are satisfied: (1) On ILP32 architectures. (2) Both LIBSA_PRINTF_LONGLONG_SUPPORT and LIBSA_PRINTF_WIDTH_SUPPORT compile-time options are enabled. (3) Width field is used with 'l' modifier. This is an implicit-fallthrough bug, but unfortunately, GCC 10.4 cannot find this out somehow... XXX Pull up to netbsd-10 and netbsd-9. netbsd-8 is not affected.
