gcc 1.32 dies with a Segmentation Violation when compiling the X.V11R3 file
	server/dix/events.c
with `-O -traditional -fstrength-reduce -fcombine-regs
-finline-functions' (Removing `-fstrength-reduce' and/or `-fcombine-regs' has
no effect).  When not using -O it dies with a self-induced abort.  Removing
the `-finline-functions' allows for successful compilation (both with or
without -O).

This is on a Sun-3/160M, SunOS 4.0.1+ with appropriate symlinks.

Stack traceback for the no -O case:

With -O, the stack traceback is:

copy_rtx(orig = 0x1), line 192 in "rtl.c"
copy_substitutions(), line 717 in "combine.c"

main(argc = 16, argv = 0xec994, envp = 0xefffa40), line 1695 in "toplev.c"

I realize this isn't too helpful; however, the size of the original source
file (105035 bytes) precludes sending a `gcc -E' output along with this report.

[ Side note: with X patches 1-7 applied, plus the Purdue patches, this is
  the *only* file that causes gcc 1.32 to blow up (using `-O -traditional
  -fstrength-reduce -finline-functions -fcombine-regs', that is) in the entire
  distribution.  This is a very encouraging sign ... ]
