From dc6d5994b4912cb00d0d183b400edfd656d6530c Mon Sep 17 00:00:00 2001 From: Gleb Mazovetskiy Date: Wed, 21 Dec 2022 11:44:27 +0000 Subject: [PATCH 1/2] Fix UB when calling cctype functions Calling cctype functions, such as isspace, with negative values is undefined behaviour. While glibc allows it, it crashes on uClibc compiled without `UCLIBC_HAS_CTYPE_SIGNED`. Fixes the undefined behaviour by casting all arguments to cctype functions to `unsigned char`. --- src/load_abc.cpp | 284 +++++++++++++++++++++++------------------------ src/load_mid.cpp | 2 +- src/load_pat.cpp | 30 ++--- 3 files changed, 158 insertions(+), 158 deletions(-) diff --git a/src/load_abc.cpp b/src/load_abc.cpp index b45f972f..8444bd87 100644 --- a/src/load_abc.cpp +++ b/src/load_abc.cpp @@ -260,13 +260,13 @@ static uint32_t abc_pattracktime(ABCHANDLE *h, uint32_t tracktime);
