I am trying to run Ruby on Rails 2.1 with Webrick on Windows Server  
2008.  
The server can start properly, but the ruby interpreter crashes after  
making  
several requests([BUG] Segmentation fault).

Has anyone experienced similar problems?

I guess it may have something to do with the address space layout  
randomization feature of Server 2008, which is the only relevant  
difference  
I can think of between Vista and Server 2008.  
[http://en.wikipedia.org/Fwiki/FAddress\_space\_layout\_randomization](http://en.wikipedia.org/Fwiki/FAddress_space_layout_randomization)

My ruby version: ruby 1.8.6 (2008-08-11 patchlevel 287) [i386-mswin32]  
1.8.7 p72 has the same problem.

If you get truly desperate and have some free time on your hands, you  
could try building the mingw version of ruby [with the -g passed in so  
that it has debug symbols] then run it under mingw gdb. Then at least  
you can have a fighting chance of finding out where the error is  
occurring. I haven’t run into it, no.
