I grew up believing that if a program is link edited as reentrant AND

what appears to be happening.
We are on z/OS 1.10. There is a non-reentrant program which, when
executed via JCL from an authorized library, fails with a S0C4. When
the failing program is physically copied to another library and
executed from there, it runs correctly. This is entirely repeatable.
Has the rule changed? Is there a "gotcha" somewhere that we are
overlooking?
What makes you think the S0C4 is caused by the program being loaded into
subpool 252?
And, since you asked about whether the rules have changed...
The system was enhanced in z/OS 1.9 to optionally protect full pages of
modules linked with the REFR option. (I think the last time that option
had any real meaning. DAT hadn't been invented yet! :-) )
Issue D PROG,REFRPROT to see if you have this option enabled...
