It's been a while but last time I looked I thought gdb's process emitted
incorrect names.  I filed this bug, with analysis:

https://sourceware.org/bugzilla/show_bug.cgi?id=24820

gdb's reader probably also needs updating, since it relies on this same
incorrect reading of the standard.

Having gdb write the index is mildly bad anyway.  It should be in the
linker, and/or dwz or debuginfod.  Putting it in gdb back in the
.gdb_index days was a mistake.
