问题
I successfully compiled and run Borealis under Fedora core 12 i386 Pentium dual core and g++ 4.1.1, Now I hope it can run under FC20 x86_64 i7 dual core. After modifying some codes(I think these modifications are nothing with its performation) and installing several additional packages Borealis needs, I successfully compiled Borealis under FC20 x86_64 and it was able to run. But when running, I found that there was severe memory leakage , gnome-system-monitor displayed using memory changed from 1.8G to 5G after it run 5 seconds. Under FC3 i386, the memory holds 200M during running.
I do not know how to start finding this cause, any advice will be appreciated!
