I have just 'banged head on' into this problem. Digging a bit deeper
into the code, I discover that the db_DELETE call is translated into:
((db->dbp)->del)(db->dbp, TXN &key, 0)
Looking in the documentation for dbopen on Tru64 (OSF/1) v5.1B I see:
...
typedef struct {
DBTYPE type;
int (*close)(const DB *db);
int (*del)(const DB *db, const DBT *key, u_int option);
int (*fd)(const DB *db);
int (*get)(const DB *db, DBT *key, DBT *data, u_int option);
int (*put)(const DB *db, DBT *key, const DBT *data, u_int
option);
int (*sync)(const DB *db, u_int option);
int (*seq)(const DB *db, DBT *key, DBT *data, u_int option);
} DB;
...
del A pointer to a routine to remove key/data pairs from the
database.
The parameter option can be set to the following value:
R_CURSOR
Delete the record referenced by the cursor. The cursor
must
have previously been initialized.
The del routines return -1 on error (setting errno), 0
on suc-
cess, and 1 if the specified key was not in the file.
Checking for the value of R_CURSOR in /usr/include/db.h I find:
#define R_CURSOR 1 /* del, put, seq */
My guess is that the builtin library SEGV's given a value of 0 for the
option parameter - which could be construed as a bug on the part of the
db-lib (I'll report that to Digi^WComp^WHP asap).
Somehow the build process will need to avoid the builtin DB-library on
Tru64 and request another one.
I'll be happy to try to help avoiding this nasty bug if I can.
A log of a build (using Perl 5.6.1) is here:
