Thanks for your report.  Indeed your program seems to have triggered a
code generation bug, which apparently has been solved in recent snapshots
and thus also for a forthcoming egcs 1.2.

  alpha[231]:~% gcc -O5 subsumption.c
  alpha[232]:~% a.out
  0
  11 1 -17 -9 -1 -1 0 -1 -1 -1 0 0 20 6 2 2 2 21 22 23 -106 4 0 
  entering:
  exit with success

  alpha[233]:~% gcc -v
  Reading specs from /home/guest/pfeifer/egcs/lib/gcc-lib/alphaev56-dec-osf4.0d/egcs-2.93.01/specs
  gcc version egcs-2.93.01 19990112 (gcc2 ss-980609 experimental)

I have installed such a recent snapshots of egcs as ~pfeifer/egcs/bin/gcc
on your machine alpha.logic.at; please give it a try and let me know how
it works for you.
