 Yes, this triggers it:
 ----------------------
 void * mempcpy (void *, const void *, unsigned);
 static char *stpcpy (char *dest, const char *src);
 
 void foo() {
   stpcpy (mempcpy (stpcpy (stpcpy (0,0), 0), 0, 1), 0);
 }
 ----------------------
 
 g/y> ~/bin/gcc-3.4-pre/bin/gcc -O0 -c dcigettext.i
 dcigettext.i:2: warning: `stpcpy' used but never defined
 g/y> ~/bin/gcc-3.4-pre/bin/gcc -O -c dcigettext.i
 dcigettext.i: In function `foo':
 dcigettext.i:6: internal compiler error: in 
 instantiate_virtual_regs_lossage, at function.c:3782
 
 I'll change the synopsis of the bug report shortly, to indicate that it is 
 not a bootstrap problem, but a problem in the middle-end.
