I'm using a Mac with a English keyboard and this issue is 100% reproducible for me - so I don't know if that is a factor.
I'm observing the same behavior Zach noted (Full system crash on window resize) in snapshot. Core i5 Macbook Air / OSX 10.8.3
Confirmed it doesn't happen for me in 1.5.2 however. Full system crash with a similar backtrace to the one noted by Kumasasa
I'm hesitant to comment twice in one day (especially since Grum was kind enough to pick up this ticket) but I've observed the following behavior and wanted to share.
I think the issue I'm experiencing might be because of the lwjgl update from 2.4.x to 2.9.0
For me personally - all releases prior to 1.6.1 didn't have this (crashing) behavior when I resized the window. However, the snapshots have shown this issue for a while now (including 13w16b, the oldest I can get from the launcher). Digging around I noticed that even tho 13w16b appears to have been released before 1.5.2 the JSON file says it uses the newer lwjgl version.
If there is any useful data I can gather any additional details to assist is resolving this issue - I'm happy to do so.
