Catastrophic error #21015: Out of memory

[Dennis Handly]

>I am able to build my source without +Onofailsafe option.

Do you get a warning saying the compile is restarting at a lower opt level?
(In future compilers, we will no longer do that if we run out of memory.)

>Is this okay to use as a workaround? OR is it worth while to try other option?

If it drops the opt level of the whole file then you'll probably get better performance if you limit the opt level drop with:
+O1=function1,function2

1.
After removing option +Onofailsafe, it builds with folloiwng warning:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Warning #21015-D: Out of memory

Warning #20013-D: Optimization aborted in function unknown. Attempting
compilation unit again but dropping the optimization level to +O1.
Please report this warning and error 21015 to HP. (20013)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

2.
I directly lowering the optimization from +O2 to +O1. With this I am able to build required object file.

3.
Then I tried to include almost all changed procedure to +O1 (+O1=func1,func2, func3, etc) in the compiler line. But, still I got same Catastrophic error #21015. So, I don't think it's too effective.

Ok, the whole file is dropped to +O1 and unfortunately it doesn't list a particular function name. Do you have lots of data initialization?

>I directly lowering the optimization from +O2 to +O1.

That's the same as +Ofailsafe.

>3. Then I tried to include almost all changed procedure to +O1 (+O1=func1,func2, func3, etc) in the compiler line.

You may have to include ALL functions and then binary search though them to remove them.

Or break up any large functions.

also look at the space available in /tmp

>Javed: also look at the space available in /tmp

Why? It would be illegal for the compiler to use space in /tmp/. It uses /var/tmp/ or $TMPDIR and then very very rarely. Use "cc -v".
error #21015: Out of memory is for swap space or maxdsiz and not disk space.

Thanks..Will check this.
