Installed Ruby 1.9.2p0 (from http://rubyforge.org/frs/download.php/72170/rubyinstaller-1.9.2-p0.exe)
on Windows 7 x64.
Create a simple Rails (2.3.8) app using mysql, and debuggin through NetBeans 6.9.
A few times the app worked fine and suddenly on refreshing a page the bug appeared.
Never seen this bug when using JRuby 1.5.1 which comes with NetBeans 6.9.

Does it work when you run without the debugger?

Yes, it does work if I simply run it, and not use the debugger

Having recently experienced these issues in 1.9.2p0 myself. I suggest testing with ruby 1.9.2p94 (2010-12-08 revision 30140) to see if they are still present.

It looks like ruby-debug19 issue. Please see https://redmine.ruby-lang.org/issues/3826#note-6
