I have tested LRA (20121014 (experimental) [lra revision 192621]) on CP2K and
find the following ICE:

Unfortunately, I don't know how to produce a small testcase, as this is
happening only for a compilation with '-fprofile-use'. I could tar the needed
mod files and .gdca if that is an option.

This is happening on x86_64:
