Well, it looks like it may be the driver after all.
In backsql_load_schema_map, everything works ok until...
backsql_add_sysmaps(oc_map); [returns ok]
ch_calloc of 0 elems of 4 bytes failed
slapd: ch_malloc.c:77: ch_calloc: Assertion `0' failed.
I'd say SQLNumResultCols is not completely implemented (or buggy) in the
Easysoft driver, but still returns SQL_SUCCESS and sets the number of
columns to 0. After that, ch_calloc tries to allocate memory for the 0
columns and fails since it's not designed for it.
Would you happen to know of another Oracle ODBC driver for Linux? :)
