Tried php4-STABLE-200501211130 and still get wrong results. The \0
issue described before could not be reproduced since the field in the
second line was longer then in the first line. But I found out, that in
all cases the \0 issue occoured, there was a date field right before the
string field and this date field contained the data from the previous
line. e.g.
1992-09-09, tho@somedomain.net
1960-01-09, tho@e-dict.net
results in
1992-09-09, tho@somedomain.net
1992-09-09, tho@e-dict.net\0net

Description:
------------
Sometimes after odbc_fetch_into($query, $row) $row contains parts of
data from the previous fetched row. For now I'm not able to reproduce
this behavior reliably, it just happens once in a while. 
What happens is that if the data of the previous row is longer than in
the current, the result contains '$currentdata\0$somepreviousdata',
e.g.
previous row: "tho@somedomain.net"
current row:  "tho@e-dict.net"
results in
"tho@e-dict.net\0net"
IOW the field is as long as the data in the previous row, contains a \0
terminator after the field content and then the rest of the previous
field.
This also happens if a unset($row) is done before calling
odbc_fetch_into()

Reproduce code:
---------------
N/A
