egcs 19990228 -O2 internal error

[Alexander L. Belikoff]

Hello everybody -

Here is the story:

1. The machine: Alpha 21264 (ev6) dual-CPU
		RedHat Linux 5.2, kernel 2.2.1 (SMP)


2. The compiler:

$ gcc -v
Reading specs from /bb/abel2/egcs/lib/gcc-lib/alphaev6-unknown-linux-gnu/egcs-2.93.10/specs
gcc version egcs-2.93.10 19990228 (gcc2 ss-980929 experimental)


3. The pristine file (preprocessed version follows):

===============================================
#include <string.h>


typedef struct foo_t {
  double foo, bar;
} foo_t;


void 
foobar(void)
{
  long maddr;
  foo_t payment;

  memcpy(maddr, (long)(&payment), sizeof(foo_t));
}
===============================================


4. The error:
