Hello, Hans.

yes

I have tried to get gcc snapshot (Feb 13th) and compile gcj with
-DLARGE_CONFIG and -DUSE_MMAP.
Well, this have not changed situation... It's weird.

I have attached gc.log which is log for GC_PRINT_STATS and out.log
which is output of program (with GC_PRINT_ADDRESS_MAP=1)

Well, I have tried cvs gcc, but it has some errors, so I got snapshot.

Please, see out.log

We have used this option too. I hope my logs will give you ideas..
Maybe I need to provide you with more information?
