gnat 3.10 on win95 -O2 problem

[William Paul Berriss <W.P.Berriss@reading.ac.uk>]

Hi

I have a proggy that runs within 50 secs when compiled
using gnat 3.07 for linux or solaris unix with -O2 or -O3
optimization. (The proggy has lots of nested for loops in it)

BUT, with -O2 optimization on gnat 3.10 for Win95
it seems to be stuck in an infinite loop near the start!!!

But if I do not use any optimization on gnat 3.10 for
Win95 then it runs just fine, taking < 50 seconds as per
normal.

So I suggest there is a problem with the gnat 3.10 for Win95
optimizer -O2

(I see no other postings here on this today)

Any advice or sharing of knowledge on this matter most welcome.

Thanks

Will Berriss
