Fail gracefully if SYSMDECK undefined or wrongly defined

With 5655-EC6 IBM Enterprise COBOL for z/OS 6.4.0, if SYSMDECK is omitted or defined to SYSOUT=*, the compiler fails with an assertion failure:


Assertion failed at ../../ibm/env/ListingAgent.cpp:6191: 0

Could not open source DD:SYSMDECK

TR_MvsCallStackIterator::TR_MvsCallStackIterator()+0x11c

TR_Debug::printStackBacktrace()+0x20

TR::assertion(const char*,int,const char*,const char*,...)+0x22e

TR_ListingAgent::writeSourceLines(int,unsigned short,int,SmartBuffer*)+0x1f8

TR_ListingAgent::generateInstructionText()+0x678

TR_zOSGlobalCompilationInfo::finishCU()+0x20ae

TRWC_compileAllSymbols+0x3298

trwc(DDTAB_TYPE*,int,char**)+0x162a

edcw+0xe44

entry64(int,int,char**)+0xc1c

main+0x3a

CELQINIT+0x1aca


This seems...wrong. It should presumably fail gracefully.
