I assume this version passes all tests? Are there any known outstanding  
bugs?  
Thanks!

Thanks a lot!

One question of mine is, is that the same as the newest svn trunk? Or  
what the major difference between them?

I have code developed in 1.9.0-1 that ran a series of benchmarks fine  
with it, but some of the benchmarks inexplicably produce SEG faults in  
version 1.9.0-2 thru 1.9.0-5. My code and benchmarks can now run with  
no problems in 1.9.1-preview1 but the benchmark times are reproducibly  
slower (by 10-20%). So its great to see 1.9.1 can run my code cleanly,  
but I hope future versions also become as fast, or faster than,  
1.9.0-1.

No. There’s a ruby\_1\_9\_1 branch now. preview 1 comes from there.

gprof is your friend–I’d post to core with this sometime.

Re: what version is preview 1  
I think it’s an SVN trunk snashot.
