the test file
I was trying to test a code generation sequence for a function in kernel, clang
crashes when trying to compile the code for user mode.
#define SEGMENT_RELATIVE volatile __attribute__((address_space(256)))
void * test_segment()
{
char SEGMENT_RELATIVE* uber_ptr = (char SEGMENT_RELATIVE *) 0UL;
return (void*)(uber_ptr + 1);
}</pre>
