Thanks for the patch!  IIRC this is something that someone reported in
the list a few months ago, right?  Would you mind mentioning the reporter
and CC anyone involved in the discussion?  If it's difficult for you to
find those, tell me and I'll do it.

Cheers,
Alex

Years ago, actually.

True :)

I found this one too: <https://lore.kernel.org/linux-man/d79b505c-5b19-331c-5b25-d40adc9cc843@wanadoo.fr/>
I've CCd that Valgrind maintainer, since he's probably interested in this.

I'll probably apply the patch tomorrow, after some sleep.

Cheers,
Alex
