#1 Core dump for tables with 101 columns

[Marcel Nijenhof]

I have a lot coredumps with gmyclient version 0.3

I can't find all the reasons why it dumps core but at
this moment it looks like it will certainly dump core
if you open a table that has more then 100 columns.

An example table is:
create table t101 (n0 int,n1 int,n2 int,n3 int,n4
int,n5 int,n6 int,n7 int,n8 int,n9 int,n10 int,n11
int,n12 int,n13 int,n14 int,n15 int,n16 int,n17 int,n18
int,n19 int,n20 int,n21 int,n22 int,n23 int,n24 int,n25
int,n26 int,n27 int,n28 int,n29 int,n30 int,n31 int,n32
int,n33 int,n34 int,n35 int,n36 int,n37 int,n38 int,n39
int,n40 int,n41 int,n42 int,n43 int,n44 int,n45 int,n46
int,n47 int,n48 int,n49 int,n50 int,n51 int,n52 int,n53
int,n54 int,n55 int,n56 int,n57 int,n58 int,n59 int,n60
int,n61 int,n62 int,n63 int,n64 int,n65 int,n66 int,n67
int,n68 int,n69 int,n70 int,n71 int,n72 int,n73 int,n74
int,n75 int,n76 int,n77 int,n78 int,n79 int,n80 int,n81
int,n82 int,n83 int,n84 int,n85 int,n86 int,n87 int,n88
int,n89 int,n90 int,n91 int,n92 int,n93 int,n94 int,n95
int,n96 int,n97 int,n98 int,n99 int,n100 int,n101 int);

If you restart the application after a core dump the
next core dump follows imidiatly after login into the
database.
