Package: gcc-4.4 Version: 4.4.4-1 Severity: normal Hi,
Citing the sscanf manpage: "The GNU C library supports a nonstandard extension that causes the library to dynamically allocate a string of sufficient size for input strings for the %s and %a[range] conversion specifiers. To make use of this feature, specify a as a length modifier (thus %as or %a[range]). The caller must free(3) the returned string[...] Since version 2.7, glibc also provides the m modifier for the same purpose as the a modifier. The m modifier has the following advantages: * It may also be applied to %c conversion specifiers (e.g., %3mc). * It avoids ambiguity with respect to the %a floating-point conversion specifier (and is unaffected by gcc -std=c99 etc.) * It is specified in the upcoming revision of the POSIX.1 standard." However, gcc -Wformat tells me: error: ISO C does not support the 'm' scanf flag BUT: it obviously knows what the 'm' scanf flag means because it warn when providing a char* instead of a char**. GCC should be updated to have -Wformat support the 'm' flag (the supported glibc-2.2 feature base is really old).
