Author: Bj旦rn G端nzel
Status: Open, Priority: Normal
ruby -v: ruby 1.9.1p0 (2009-01-30 revision 21907) [i386-mswin32]

I have installed the binary distribution of Ruby 1.9.1 for Windows XP and tried to run rdoc on the source snapshot from today as follows: 

rdoc lib ext -o rdoc -S -T kilmer

After quite a while this fails with "NoMemorError", see copied output below. My PC has 4GB of RAM installed. The same command has completed successfully on the same machine with Ubuntu Linux 9.04 64 Bit Edition.

Output:
