[Bug c++/19761] -Winit-self doesn't work anymore
--- Additional Comments From pinskia at gcc dot gnu dot org 2005-05-31 02:41 --- No you are thinking wrong, it will be the same warning as it is uninitialized, the flag just turns on the warnings for those cases. -- What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||WONTFIX http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19761
[Bug c++/19761] -Winit-self doesn't work anymore
--- Additional Comments From oliverst at online dot de 2005-05-31 01:29 --- Yes, I did expect a different warning, because int i = i; would be uninitialized use and self initialization. And because of an special warnings flag I expected it to be different from the uninitialized use warning. But if it causes the same, it should be part of -Wuninitialized and -Winit-self would be kind of redundant then. Maybe I am just seeing this totally wrong. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19761

--- Additional Comments From dannysmith at users dot sourceforge dot net 2005-05-30 21:03 --- I can't reproduce this with either gcc-3.4.4 or 4.0.0 on mingw The example gives the warning warning: 'i' might be used uninitialized in this function iff I add -Winit-self That is consistent with manual. Are you expecuning a different warning? Danny -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19761

--- Additional Comments From oliverst at online dot de 2005-03-31 11:35 --- I tried it again with this GCC: Using built-in specs.

I also tried it with "-Wno-unitialized" to see, if that warning somehow disables the -"Winit-self", but I still don't get the expected warning. Sorry, but reopening this bug. Maybe we should get a third opinion (another guy with a 3.4.x or 4.0.x GCC) on this.

strange...I just tried it again with this example:
extern void foo(int);
int main()
{
int i = i;
foo(i);
return i;
}
And I get only this (C and C++ front-end / -O1, -O2 and -O3):
$ gcc -Wuninitialized -Winit-self -O1 test.cpp
test.cpp: In function `int main()':
test.cpp:5: warning: 'i' might be used uninitialized in this function
Maybe it was fixed between GCC 3.4.2 and GCC 3.4.3? Or it's a target-specific
problem? I unfortunately don't have a linux GCC 3.4.2.
