>Description:
pedantic gives a warning when a jump jumps over the initialization of a var, but then dies. Without pedantic, is gives an error. The error is ok, but the warning is confusing. It should be an error too.
[michiel@epsilon temp]$ cat goto.cpp
int main() {
goto label;
int temp = 1;
label:
return 1;
}
[michiel@epsilon temp]$ g++ -pedantic goto.cpp && echo ok
goto.cpp: In function `int main()':
goto.cpp:6: warning: jump to label `label'
goto.cpp:2: warning: from here
goto.cpp:4: crosses initialization of `int temp'
[michiel@epsilon temp]$ g++ goto.cpp && echo ok
goto.cpp: In function `int main()':
goto.cpp:6: jump to label `label'
goto.cpp:2: from here
goto.cpp:4: crosses initialization of `int temp'
[michiel@epsilon temp]$
(expected: echo "ok" when only warnings are given)
