As reported here: https://sourceware.org/ml/gdb/2018-02/msg00019.html the type of values representing static members that are optimized out is wrong. It currently assigns the type of the containing class rather than the type of the field. This patch fixes that. I found a place in m-static.exp already dealing with optimized out static members, so I just added some gdb_test there. gdb/ChangeLog: * value.c (value_static_field): Assign field type instead of containing type when returning an optimized out value. gdb/testsuite/ChangeLog: * gdb.cp/m-static.exp: Check type of optimized out static member.
