>Description:
	The compiler (g++) takes almost a minute and uses 350 MB of memory
        while compiling the following program with only the -c flag:

struct X
{
  int a[5000000];
};

        I tried this with two PCs running Linux. The CodeSourcery's online
        test compilates reported "virtual memory exhausted".

>How-To-Repeat:
        Compile the struct definition above with "g++ -c"
