--- Comment #1 from Petar Jovanovic <[email protected]> ---
GDB 17 computes TLS addresses itself. With a remote target it no longer asks
the stub via qGetTLSAddr. Instead it reads the thread pointer from the fs_base
register (feature org.gnu.gdb.i386.segments) and walks the DTV in memory.
Valgrind's amd64 gdbserver has never exposed fs_base, so the lookup fails. GDB
16 and older still use qGetTLSAddr and are not affected.
