Thanks a lot for this bug report.

I tried this code with 1.42 version (it failed with an assertion),
trunk (sigfault), release/branch(sigfault) and with 1.46
(bad_lexical_cast exception). It is an old bug and if this bug is not
critical for you, I think it can wait till next release (1.49).

I`ll create a ticket with bug description.
