Mikhail,

On which system have you tried to start it?
I can't say I was so lucky. Today I've tried to start jEdit (I have
the most recent stable version 4.2) several times on my Debian Linux
(32bit) system.

First time it hanged after pressing couple of buttons with:
free(): invalid pointer 0x<some hex number>
free(): invalid pointer 0x<another hex number>

When I started it again it crashed with:
SIGSEGV in VM code.
Stack trace:

I don't want to say that jEdit is the best possible reproducer. Just
like to reminde that we still have problems with it.

With Best Regards,
