Hi!

Running a binutils/GDB build on an up-to-date Debian GNU/Hurd system, I
just hit (mostly manually transcribed):

    ext2fs: ../../libports/../libshouldbeinlibc/refcount.h:165: refcounts_ref: 
Assertion `! (r.hard == 1 && r.weak == 0) || !"refcount detected 
use-after-free!"' failed.

Unfortunately, it was the root filesystem, so I couldn't start GDB to get
a proper backstack, etc.

Justed CCed, as you've "lately" ;-) (in "Hurd timescale") been changing
some code using these refcounts -- just in case you'd happen to have any
suspicion.


Grüße,
 Thomas
