cannot list the pathname of my own modules in backtrace on mswin64

Added by usa (Usaku NAKAMURA) about 14 years ago. Updated over 13 years ago.

Status:
Closed
Target version:
ruby -v:
ruby 1.9.3dev (2010-09-29 trunk 29360) [x64-mswin64]
Backport:

(1) ベースアドレスを正しく取得できていない
(2) その仮定はx64版Windowsでは成り立つとは限らない
のいずれかの理由によってうまくいっていないようです。

以上、自分が後で思い出すためのメモでした。
