Summary:
SYMPTOMS
DB-LIBRARY (db-lib) programs compiled with /Zp (pack structure
members) produce general protection (GP) faults and incorrect
results. The problem seems to be limited to db-lib macros such
as dbcurrow(), dbfirstrow(), and dbrowtype().
CAUSE
Db-lib has been compiled with default structure alignment. If the
user program is compiled with an incompatible pack option, db-lib
macros will be generated with incorrect offsets, resulting in
unpredictable results.
RESOLUTION
If the user program must be compiled with /Zp, the problem can
be circumvented by putting pragma statements around the include
for "sqldb" to force word alignment offsets to be generated when
db-lib macros reference that structure.
