webrev : http://cr.openjdk.java.net/~ghb/8157145/webrev.00/ Root cause : 1. Missing implementation of setCapHeight 2. Due to FontMetrics::m_capHeight wasn't initialized to default value in its constructor and it was expected to be set from platform specific implementation from "Font::platformInit()". FontCascade::floatWidthForSimpleText was returning infinite value "1.#INF00" Solution : r173217 "Letters size to a specified number of paragraph lines, and align to the cap-height of the first line and the baseline of the last line.". Added the setCapHeight from PrismContext (WCFont). GTK has implemented in http://trac.webkit.org/changeset/174002. (By setting the cap height) Test : executed the DRT (fast/css-generated-content/initial-letter-basic.html) for ~10 times (windows x64) and same content from in HelloWebView 10 times didn't see any crash.

I ran the specific test case on Mac and wasn't able to reproduce the crash. I can reproduce it intermittently on Windows x64.
