| 1206.2 | Fixed | TLE::EKLUND | Always smiling on the inside! | Fri Feb 28 1997 14:35 | 14 |
| I could reproduce this problem readily. It seems to
have been fixed (late January), for our compilers since
that time do not exhibit the bug. Dropping the optimization
level to 4 (or lower) seems to avoid the problem in the
meantime.
Cheers!

PS As always, thanks for the simple example and the
command line! Makes things ever so much easier!

| Dave,
When is the next bump for the compiler where we can have TMA build with
-O5? The partner requires a homogeneous build environment, so we are
using -O4 exclusively for now, and want to test/recommend -O5.
Note that Robert Shen has opened OSF_QAR 51789 -- please close ;-)

| Our current plan is to do an "ECO kit" for at least the UNIX platform, and
maybe VMS (more to keep things the same out there) in late March or early
April, but this is subject to change based on whether or not we want to wait
for a particular bug fix.
