Hello Stefan,

I today tried to reproduce this with current git master. It worked for me ok in the simple test 
case

 0(12121) DEBUG: pdb [pdb.c:239]: pdb_query(): querying '495041748'...

There is (unfortunately) no version output in the help, should be added. You can check with 
strings

git master version:
$ strings pdb_server | grep -i version
version = %d
PDB_VERSION_MAX
PDB_VERSION_1
version
pdb_versions
.gnu.version
.gnu.version_r

4.3 version:
strings ./pdb_server | grep -i version
.gnu.version
.gnu.version_r

Best regards,

Henning
