[M3devel] open array allocation problem?

[Dragiša Durić]

It happens with same code on three platforms and two versions... I can
send you my source to try to debug it - m3gdb frustrates me a lot these
days... 

Is it working at all? Or maybe on some of my platforms it is worth a
try? (m3gdb)

TIA,
dd
