I found that the program does not crash even with +O2 optimization when I set the inline option to zero (using "+inline_level 0" or "+d"). I understand that inline functions sometimes improve the speed but still don't see why using them could lead to a crash if everything else is OK with the program.

I also understand why the program might be not crashing now. By disabling inlined calls, I moved some code around and the problem (if it exists) could be just hidden now. Any ideas, or information on inline function calls with aCC in HP UNIX? Anyone has experience when making function inline would lead to a crash or knows about problems aCC has with inline calls?

Thanks.
