- Reply-to: gcc-bugzilla at gcc dot gnu dot org
The following code compiled as C++ (does not happen when compiled as C), issues
a wrong warning:
void test()
{
unsigned int i = 0;
int val = i ? i : -1;
}
$ gcc -c test.cpp
test.cpp: In function `void test()':
test.cpp:4: warning: converting of negative value `-0x000000001' to `unsigned int'
My GCC version:
Configured with: ../gcc/configure --with-gcc --with-gnu-ld --with-gnu-as
--host=mingw32 --target=mingw32 --prefix=/mingw --enable-threads --disable-nls
--enable-languages=c,c++,f77,ada,objc,java --disable-win32-registry
--disable-shared --enable-sjlj-exceptions --enable-libgcj --disable-java-awt
--without-x --enable-java-gc=boehm --disable-libgcj-debug --enable-interpreter
--enable-hash-synchronization --enable-libstdcxx-debug
Thread model: win32
gcc version 3.4.2 (mingw-special)
I does also happen with MinGW GCC 3.3.3 and 4.0.0 (20040925) and linux GCC 3.2.
