Package: gcc-3.2 Version: 1:3.2.3-0pre9 Severity: wishlist the following code (compiled with -Wall -pedantic) could be considered "buggy", because it implicitly converts a signed int to unsigned int when calling "a". if you run it, it will print the number 2^32-1 instead of -1.
#include <stdio.h> int a (unsigned int b) { return printf ("%u\n", b); } int main () { return a (-1); } this can lead to programming bugs. to prevent a programmer from such, i'd appreciate if gcc said something like: warning: implicit conversion from signed to unsigned when asked to compile this code. maybe it makes sense to warn about conversion from unsigned to signed too, although having problems with this is unlikely, since bit overflow only happens with really big numbers. -- System Information: Debian Release: testing/unstable Architecture: i386 Kernel: Linux aragorn 2.2.22 #1 dl nov 25 21:59:43 CET 2002 i586 Locale: LANG=ca_ES.ISO-8859-1, [EMAIL PROTECTED] (ignored: LC_ALL set) Versions of packages gcc-3.2 depends on: ii binutils 2.13.90.0.18-1.7 The GNU assembler, linker and bina ii cpp-3.2 1:3.2.3-0pre9 The GNU C preprocessor ii gcc-3.2-base 1:3.2.3-0pre9 The GNU Compiler Collection (base ii libc6 2.3.1-17 GNU C Library: Shared libraries an ii libgcc1 1:3.3-0pre5 GCC support library -- no debconf information
