Hi all,
This week I installed Lion (and I’m now regretting it). I find the following problem which was not present with Snow Leopard:
root [0] TBrowser b
*** Break *** segmentation violation
===========================================================
There was a crash.
This is the entire stack trace of all threads:

I tried recompiling the latest ROOT (v5.30.01) but the problem persists. I suspect there is an issue with X11 in Lion as I also have some problems when forwarding X sessions over ssh. Has anyone else experienced this problem and can suggest a fix?
Thanks,
Greig
