Re: Error build with option -O
My suggestion would be to split sv.c into two, svc1.c and svc2.c. Compile one with -O and one without. See if it works, swap to compiling the other with -O if necessary. Repeat that process to binary chop and find out exactly which function in sv.c is failing. If you can narrow down to a simple test case even better. Or another approach: if you still have access to an older version of z/OS can you compile sv.c with the assembler listing option on (-Wc,list) then do the same with z/OS 2.02 both with and without -O and then we can do a diff. (I found a bug in the latest metal C compiler just recently using this approach. Use "cut" to get rid of unwanted junk from the listings).

This can be from 1) a bug in the new compiler, though my experience is that this is unlikely. 2) an alignment issue 3) use of some construct which has undefined behavior, but the earlier compiler gave the expected behavior. 4) probably lots of other things. If there exists some tool that looks for out-of-bounds kinds of things, I'd start with that. valgrind or purify or various other ones are available on some systems. Getting a stack trace would be helpful. Opening a file in C and writing the invalid version object out to it might be helpful.
