Bind 9 and sdb

[jps]

Hello,

has anyone tried successfully to use the postgres sdb sample
provided with bind 9 (up to 9.1.1rc2) ?

I used the zonetodb program to convert a working zone file
into a postgresql database, and recompiled bind9 to add
pgsqldb.c support (without any changes).

it works fine:
- when I dig 'ANY' my local zone.
- when I dig 'A' records for hosts within this local zone.
- when I dig 'NS' records for delegated sub-zones.

but when I dig 'A' records for any of the sub-zones:

Program received signal SIGSEGV, Segmentation fault.
dns_rdata_clone (src=0xdededede, target=0xdededede) at rdata.c:369
369             REQUIRE(DNS_RDATA_VALIDFLAGS(src));

with this backtrace:

any idea ?
