Crash in put_wc

[MarSoft]

Another sporadic crash. Last time it happened when I ran git diff in one of the active windows, but I don't know what could cause that.

Tried to debug it with gdb and found that the problem happened in dvtm/vt.c line 1393, and that b->curs_row->cells was 0x2000000000 which is obviously not the correct memory address.
