I was wondering whether there was a good Mark> description of the issue and/or a bug report for it. 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. Tom
