The documentation says that this message can appear even if some part of the statement will not be executed, but that would be rather strange here, as va_end() is a builtin. -- System Information: Debian Release: testing/unstable Architecture: i386 Kernel: Linux pc-debian 2.4.21-1-k7 #2 Mon Jun 16 22:23:16 EST 2003 i686 Locale: LANG=C, LC_CTYPE=C Versions of packages gcc-3.3 depends on: ii binutils 2.14.90.0.4-0.1 The GNU assembler, linker and bina ii cpp-3.3 1:3.3.1-0pre0 The GNU C preprocessor ii gcc-3.3-base 1:3.3.1-0pre0 The GNU Compiler Collection (base ii libc6 2.3.1-17 GNU C Library: Shared libraries an ii libgcc1 1:3.3.1-0pre0 GCC support library -- no debconf information
