You can chalk one more up to the compilation problems on the RS6000!


I recently updated our copy of gcc on our RS600 (AIX 3.2.4) to V2.5.7 (from
2.4.5) and have been getting illegal instruction and unrecognisable instruction
errors (Examples below).  The strange thing is that these some of these errors
do not always seem to occur; the code may compile fine one time in 20 (for 
example, I had one more error to list below, but when I recompiled to capture
the errors to a file, it went away).  Is this a known bug (and is there a 
patch)?	  I built gcc with 4 stages the first time (the make compare after 
stage2 went fine); the first time I bothered with the extra passes.  Thinking
this may have been my downfall, I then re-compiled using three stages the way
I have for years now, but the errors are still there.

Bugs & Fishes,

Roy

BTW:  These examples are from Sam Leffels Flexfax-2.2, which compiled fine 
under gcc V2.4.5.
