--- Comment #1 from myocytebd at sina dot com ---
The problem seems fixed with latest snapshot.
Updated bug description:
gdb-7.6, Ubuntu 13.10
whole program: ~10min
one library: extremely slow (> 1 hour; killed)
gdb-7.8, Ubuntu 14.10
whole program: extremely slow (> 1 hour; killed)
one library: extremely slow (> 1 hour; killed)
latest gdb snapshot, Ubuntu 14.10
(configured without no options)
whole program: ~2min (a lot faster; the annoying seek hotspot seems no longer)
one library: good (faster than whole program; the annoying seek hotspot seems
no longer)
The whole program is ~1.5M symbols,
with three heavy libraries ~400k each.
