Hello

While building ruby 1.9.1 on a Debian Lenny box with gcc4.3 (the  
default) compiling parse.c might take several minutes on decent  
hardware.

This problem happens on multiple x86 and x86\_64 boxes for me but does  
not happen on Debian gcc maintainer’s boxes.

gcc 4.2 works fine for me.

Anybody else sees this problem?

Thanks

Michal

I just built 1.9.1 successfully with gcc 4.3 on openSUSE 11.1 (64-bit  
machine). I haven’t done much with Lenny recently, although I will  
probably download it when it’s release and build a virtual machine  
with it.

I’ve never met a happy clam. In fact, most of them were pretty steamed.

It’s not that it does not build, it’s just that it compiles that  
particular file for very long and causes a particular pattern appear  
on graphical system monitors that normally appears when something  
locks up in a tight loop.

Thanks

Use optflags=-O3 instead of default -O2.
