Description:
>>> DblqMain.cpp
>>> ------------
>>>
>>> ScanRecordPtr sp;
>>> sp.i = recordNo;
>>> c_scanRecordPool.getPtr(scanptr);
>>> if (sp.p->scanState != ScanRecord:confused smileyCAN_FREE){
>>>
>>> sp.p is not initialized
`

How to repeat:
read source

Suggested fix:

change 
  c_scanRecordPool.getPtr(scanptr);
to 
  c_scanRecordPool.getPtr(sp);

Many thanks for writing a bug report.

I can't find this in our actual source code anymore but I found similar curiosity and another row:

18810: ScanRecordPtr sp;
18811:    sp.i = recordNo;
18812:    c_scanRecordPool.getPtr(scanptr);
18813:    if (sp.p->scanState != ScanRecord::SCAN_FREE){
