Package: bibtool Version: 2.55+ds-2 Usertags: goto-cc While compiling the package using our research compiler infrastructure it became apparent that the following declarations are conflicting: http://sources.debian.net/src/bibtool/2.55%2Bds-2/include/bibtool/type.h?hl=318,327,336,341,342,343#L318 Observe that the definition with internal linkage is for unsigned char, whereas all three external ones are plain "char." Not only do Debian's platforms vary in terms of signedness of char (so this will be consistent on some, but not on others), but also this is worrying if ever any unicode characters (with a character code beyond 127) are to be considered. Furthermore the compiler may make various inconsistent assumptions, possibly causing undefined behaviour. It seems a full code review is due with respect to char vs. unsigned char, as this appears to get mixed. Best, Michael
