Created attachment 24796
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24796
full testcase source with required files from Crypto++ 5.6.1 and build command

the (slightly modified) testcase with Crypto++ 5.6.1, this time self-contained.
All files except gcc_pr49140.cpp are unmodified form Crypto++.
build command is in build.sh, with option -save-temps.
