It would be helpful to get the stack trace as well as the test case
(i.e., a subset of the header you are compiling) that reproduces the
problem.

To get the stack trace, re-run the ODB command with '-x -dH', for
example:

$ odb -x -dH ... test.hxx

This should produce the core file. To analyze it, run:

$ gdb -ex backtrace "$(g++ -print-file-name=cc1plus)" core

This should produce the stack trace. Please include it with the
test case.
