Hi,
after I applied the patch for the buffer overflow in [1], I found another one due to txt_convoi_value also being to small. This caused another crash when building with hardening flags and choosing Russian.
Please consider applying the attached patch.
Regards,
Ansgar

Increase, but imho this should be changed to money2string and buffer to avoid furhter bufffer overflows ...
