Summary: invalid pointer freed in fontmap.c

free (l);
can free a pointer invalidated by modifications
after assigning from malloc; and it does in my case.
should be:

This is probably some GCC stack protection extension that's not available
or active on all systems ...

Oh,
thanks for your attention.
By the way, how did this bug survive?
xdvi did not even start on my computer, (i386, arch linux, current)
yielding an error about attempting to free an invalid pointer.
