Hi,
Now that we have -Wvla set:
===
Adds C++ warning flag for C Variable-Length Arrays.
C VLAs are not supported in C++. However, the GNU compiler allows
them as an extension, which it does not warn about when not in
pedantic mode. Unfortunately, it's easy to accidentally write
a VLA, even unintentionally-- adding this warning will help us
catch that.
===
Are there going to be attempts to eradicate this usage?
Note that Clang also supports VLAs:
===
GCC and C99 allow an array's size to be determined at run time. This
extension is not permitted in standard C++. However, Clang supports such
variable length arrays for compatibility with GNU C and C99 programs.
