Buffers over 1Mb fail, hang or SEGV

[DuncanCragg]

Hi, I was using v0.13-2 on Ubuntu and hit an issue where buffers over 1Mb cause this command to either return all zeros, or simply to hang or SEGV:

xclip -selection c -o -t text/html | wc -c

It sometimes works above 1Mb, but mostly doesn't.

This seems most likely related to this issue: #43

I ran the original poster @rogpeppe's script and it behaves the same for me:

dd 'if=/dev/zero' 'bs=1' 'count=1048576' | tr '\000' 'a' | xclip -selection c -i

xclip -selection c -o | wc -c

.. gives zeroes or hangs, but:

dd 'if=/dev/zero' 'bs=1' 'count=1048575' | tr '\000' 'a' | xclip -selection c -i

.. always works, with one char short of 1Mb.

I grabbed the sources from here on Git and built but it's the same version with the same issue! I built the "xerror" branch as mentioned in the issue mentioned but no joy.

I'm very happy to help out and investigate and try things as I can reproduce it quite reliably.

Hi I seem to be experiencing the same issue as well, but what's weird in my case is that this happens only, and reliably, when I'm running the Qtile window manager; I consistently can't get it to reproduce under Openbox or dwm. I'll dig deeper and see what else I can find
