I have a question about the following patches.

patchSG0000556.c++_dev_sw  07/26/95  C++ Software
patchSG0000556.c++_dev_sw.c++  07/26/95  C++ Compiler

What are the aims of these?

There are some incompatibility problems in running our C++ program.
The executable code made by C++ with the above patches runs fine,
however, the executable made by C++ on another indigo2 without the
patches gives wrong results.
We are also curious that the size of the executables are different,
the former one is almost one third of the latter though the source
programs are completely the same.  In addition either one is not
stripped.  That's why I am suspecting the presense of the patches.

Any pointers will be welcome.  Thank you.

To fix bugs? Or are you referring to some higher purpose?  Many, many bugs
have been fixed in patch 556. Read the release notes for the patch (try
"grelnotes patchSG0000556").

No surprise - if that other Indigo2 didn't have the patch, chances are that
you are running afoul of a bug that's been fixed in patch 556.

One-third?! Wow. There was this bug in patch 170 (an early predecessor of
patch 556) which caused some bloat, but nothing like this (it was more like
5%).

Are you *SURE* you compiled exactly the same files with exactly the same
options (i.e. -g .vs. -O, etc)?
