Then if you run :
valgrind pd vbap-help.pd
and click around a bit, you get :
Actually that's a different bug than the one you found, but that's a bug
anyway, and it's the kind of thing that can cause a crash later (e.g.
while closing a patch), though I don't know how to get it to really crash.
I made two mistakes... I forgot to paste that there's an Invalid Write of
same size at the same place in the programme, just after the Read... a
Write is more dangerous.
The other mistake, of course, is that at one point I switched from trying
rvbap-help.pd to trying vbap-help.pd without even noticing. With
rvbap-help.pd, I get this crash instead :
