Hi, I have been playing with the undotree() function lately. Unfortunately, it didn't take long, until it crashed :(
Here is a way to reproduce it: chrisbra t41:~/vim [1016]% vim -u NONE -N -c ':echo undotree().entries' Vim: Caught deadly signal ABRT Vim: Finished. zsh: abort vim -u NONE -N Here is the backtrace: Program received signal SIGABRT, Aborted. 0xb7fe2424 in __kernel_vsyscall () (gdb) bt #0 0xb7fe2424 in __kernel_vsyscall () #1 0xb7e2e751 in raise () from /lib/i686/cmov/libc.so.6 #2 0xb7e31b82 in abort () from /lib/i686/cmov/libc.so.6 #3 0xb7e6522d in ??

Run vim like this (it doesn't matter, whether you have persistent undo information for the file you are editing): ~$ vim -u NONE -N :let a=undotree() :echo a.entries :echo a.entries (I couldn't make a script, that "successfully" crashes).
