Well, the CommandCounterIncrement call is either in postgres.c line
1032, or in the finish_xact_command call in line 1024 (may I suggest a
breakpoint in CCI while reproducing the bug?). I'm not sure I
understand your (b) argument (if we failed to produce a sinval message
for this then the bug would have been detected eons ago), so I think the
most likely explanation is (c) :-)

Yep. No luck. I didn't try changing the args in generate_series though.
How many CPUs are you running this on? My system has 2.
