I stumbled upon below error message from the IBM COBOL compiler for mainframe:
IGYRC5108-U COBOL COMPILER TERMINATING: UNCORRECTABLE PROGRAM INTERRUPT CONDITION.
The COBOL program was not fully compiled but compilation stopped midway.
Further messages from the compile run:
PROGRAM CHECK, INTERRUPT CODE 04

Compiler in question is "Enterprise COBOL for z/OS 6.3.0".
Searching for this error message brought below entry from IBM: IGYRC5108-U COBOL Compiler Error Message for Phase IGYCPSCN. This is not pointing to the real cause.
The real problem is that you have used too much space in WORKING-STORAGE SECTION.
I.e., your variables in there consume too much space.
When remembering Memory Limitations with IBM Enterprise COBOL Compiler this comes as no shocking surprise.
So reducing this occupied space solved the problem.
In my case I had a couple of large PIC X(256000) clauses.
