gcj-dbtool segfaults on hppa-linux-gnu and arm-linux-gnu; arm doesn't have libjava support yet; the patches available from http://gcc.gnu.org/ml/java/2006-08/msg00123.html were used. rechecked both with a new 4.2 as a debian package and a vanilla upstream build. the installed gcj-dbtool crashes. I don't see the segfault, when gcj-dbtool is called during the build. GNU gdb 6.4.90-debian Copyright (C) 2006 Free Software Foundation, Inc.
