I haven't had the time to recompile with -ggdb, but my version was
compiled with -g. So I ran d.what.vect through gdb and behold: it works
like a charm !
To make it clear:

I run d.what.vect once: no problem, I quit.
I run it again: no reaction on first click, command terminates on the
second click.
I run gdb $GISBASE/etc/bin/cmd/d.what.vect, then "run" and it works
perfectly, even rerunning it several times.

Any explanations ? Do you still want me to recompile with -ggdb ?
