Hi, Here is one trivial initialization fix and another patch to convert a huge macro to an inline function. The result of the expansion would show up in an assertion which triggered a -Woverlength-strings warning.

This is, hopefully, a full fix for handling of li-records. See: https://bugzilla.redhat.com/show_bug.cgi?id=717583 https://bugzilla.redhat.com/show_bug.cgi?id=987463 Rich.
