transactions are in the middle of compilation can result in
various -901 SQLCODEs or traps as the table packed descriptor
may be removed from memory while being accessed.
Example symptoms include
Traps with the following stacks:
sqlcode -901:
"Invalid collation ID" from sqlnq_get_collation
"qunp has more columns then base table" from
sqlng_build_colRefs_obj
