hi,
i have a large c++ application (2.9GB of shared objects, 600MB of static
archives used in shared objects). on isolated part of sources a single
'next' call takes ~3 minutes and increases memory usage from ~500M to ~3G
while previous gdb-7.3.1 needs only 2..3 seconds and increases memory usage
from ~400M to ~550MB.
