Hi,

The following lines of input cause the cc1 module of gcc to die with
a fatal error message, citing signal 6, when the compiler is compiled
to run under the i386-sysv configuration on AT&T 6386 computer running
System V.3.2.  I have traced the source of the error to expr.c, in
the routine emit_move_insn().

This is the smallest I could make the test case.   The bug disappears when
structure members are removed or made into a different type.

Any help you could give would be appreciated.  My work # is 617/225-1618
if you have any questions.
