I tried to compile the following trivial program, called 'hello.c':
#include stdio.h
int main(void)
{
printf(hello, world!\n);
return 0;
}
using gcc, in a directory which had a subdirectory called gcc. This caused
the compile to fail with the following output:
gcc hello.c

Confirmed. We seem to be very slowly eating all of memory during processing

What exactly do you mean with redundant stack manipulation? Note that the

stack adjustment necessary before the call. Note also that you
