Following up to myself, I finally understood my problem: I was trying to
re-use SPI_tuptable->vals[i] after calling SPI_exec() on another,
unrelated query. So the backend crash makes perfect sense now.

What is the best strategy: 
- store the result of a SELECT returning multiple tuples into a local SPITupleTable? How do I allocate memory for
that?
- iterate over all values contained in the tuples and store _them_ into char**, int*, arrays, before re-running
SPI_exec()on the second query?
 

TIA
