[tools-compilers] C99 variable-length array and lint warning

[Kacheong Poon]

I have a question about lint warning on the following code.

int foo(void)
{
  ...
}

int bar(void)
{
    int a[foo()];
    ...
}

Lint complains that the return value of foo() is ignored.
Isn't the above a valid way to use the variable-length
array feature (assuming it will not cause stack overflow)?
Or is it an issue in lint?  The lint is

lint: Sun C 5.9 SunOS_i386 Patch 124868-10 2009/04/30

Thanks.
