Bug ID: 68266
Summary: pointers to arrays of excessive size not diagnosed
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
Target Milestone: ---
In C mode, GCC issues an error for pointers to arrays of excessive size such as
the one in the program below. However, in C++ mode, it fails to diagnose the
same invalid constructs.
$ cat u.cpp && /build/gcc-trunk-svn/gcc/xg++ -B /build/gcc-trunk-svn/gcc -S
-Wall -Wextra -Wpedantic -o /dev/tty u.cpp
typedef __typeof__ (sizeof 0) size_t;
typedef int (*A)[__SIZE_MAX__];
.file "u.cpp"
.ident "GCC: (GNU) 6.0.0 20151108 (experimental)"
