[PATCH] Fix SystemStackError when trying to format a large block of text in REXML
|ruby -v:||ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-openbsd4.8]||Backport:|
REXML::Formatters::Pretty#wrap used a recursive method call to format text. This patch switches it to use an iterative approach. It includes a test case exposing the error.
This issue isn't theoretical, it happens when using rcov with Sequel's test suite.
Tested on 1.9.2p0, but patch is against trunk.
