psql-reader null pointer dereference?

[Ben Pfaff]

I ran clang-analyzer (http://clang-analyzer.llvm.org) on the PSPP
source tree and here is the report:
        http://benpfaff.org:8181/

Some of the reports are correct.  Others are false positives.  I
am not sure about the ones for psql-reader.c (which are all quite
similar):

        http://benpfaff.org:8181/report-sP82Pb.html#EndPath
        http://benpfaff.org:8181/report-nSLyIM.html#EndPath
        http://benpfaff.org:8181/report-h6avCn.html#EndPath

They look plausible but I don't understand the code well enough
to say for sure.  Can you take a look at those (and any others
that you would like to)?
