>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"
