Sorry for the late response.

Unreproducible for me, so more information is needed in diagnosing
the cause of the problem.

Thanks,

So it still looks bad.

Control: tags -1 - unreproducible
Control: retitle -1 w3m: lots of GC Warning: Repeated allocation of very large block on i386

Reproducible on i386, not on amd64, though fixing seems not so easy.
