Bug ID: 68113
Summary: VLA+typeof+new -- confusing warning
Product: gcc
Version: 5.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ch3root at openwall dot com
Target Milestone: ---
Compilation of the program:
int main()
{
int n = 1;
int a[n];
new __typeof__ a;
return 0;
}
with just `g++ vla-typeof-new.cpp` outputs:
vla-typeof-new.cpp: In function ‘int main()’:
vla-typeof-new.cpp:5:18: warning: non-constant array new length must be
specified without parentheses around the type-id [-Wvla]
new __typeof__ a;
^
Perhaps the code is invalid but the warning is kinda confusing (there are no
parentheses here:-)
