When I run latest trinity at a stable 32 Bit Gentoo Linux user mode linux image I do now get :

If you could narrow down which syscalls are causing this it would help a lot. scripts/find.sh might give you some ideas.

will do - where's the variable $i (line 32 and 33) defined in find.sh ?

Are you running as root ? Probably best to just -x it for now.

sanitise_move_pages could use rewriting tbh, to use the new maps structs. I'll look at doing that in the new year.

With latest git tree 1.1-946-g7f333fd I cannot blame a single syscall for emitting the glibc error. I tried it with this command line (as a common user) :
$> for sc in trinity -L | grep entrypoint | grep -v AVOID | awk '{ print $3 }' | sort -u; do echo $sc; trinity -q -c $sc -C2 -N 9999 2>&1 | grep -B 4 -A 4 libc; sleep 2; don

So, it is either a combination of 2 or more syscalls (and ofc ML might be a culprit too).

BTW, the tag "v1.3" seems to be a light weight tag, right ? Because git describe" still refers to v1.1-..."

good to know. I've still got a bunch of other backtraces to dig through, but that's going to have to wait until next week.
