What do you mean with trunk? It still doesn't warn for
g++-4.9 (Debian 4.9.4-2) 4.9.4`
g++-5 (Debian 5.4.1-4) 5.4.1 20161202`
g++-5 (Debian 5.5.0-8) 5.5.0 20171010`
g++-6 (Debian 6.3.0-18) 6.3.0 20170516`
g++-6 (Debian 6.4.0-12) 6.4.0 20180123`
g++-7 (Debian 7.2.0-16) 7.2.0`
g++-7 (Debian 7.3.0-3) 7.3.0`
Ah okay this version does work:
g++-8 (Debian 8-20180207-2) 8.0.1 20180207 (experimental) [trunk revision
257435]
although I don't see why this can't be a minor version bugfix in the older
major versions:
shadowtest.cpp: In member function ‘int f::g(int)’:
shadowtest.cpp:3:24: warning: declaration of ‘mVar’ shadows a previous
local [-Wshadow]
int g(int x) { int mVar=3; return x+mVar; }
^~~~
shadowtest.cpp:2:16: note: shadowed declaration is here
static int mVar;
^~~~
Btw offtopic, aren't all these major version upgrades too much too fast? I've
lost quite a bit of time, because my system didn't work with g++5 (kernel
module didn't compile), or because CUDA didn't, or because I had
ABI-incompatibility bugs, because I linked code compiled with different
compiler compilers accidentally and the list goes on ...
