This looks like a runtime initialization problem. Class.forName(), and subsequently, VMClassLoader 
is being called from inside _Jv_CreateJavaVM, but the File.separator field has not yet been set.

1. Does a "hello world" program work ok? 

2. Can you try this with the current CVS code?

3. Can you narrow this problem down to a small test case?

No, same error. Good Question! I was stupid to not tested myself.

No, I tried, but I seems to have difficulties to compile it:

OK, so it must be something caused by your configuration or 
environment. What linux distribution is this on? And are you using the 
distribution's gcj or did you compile it yourself?

Try configuring with --enable-languages=java - this will only build the 
C, C++, and java compilers so problems with ada will be avoided (and 
the build will go a bit faster)

FYI my configure command is:

./configure --prefix=/home/bryce/gcc --enable-languages=java 
--enable-java-awt=gtk --disable-static

I compiled myself. I'll try cvs again.

Well, something is very wrong here - looks like a problem with your 
system/glibc headers?

Not very wrong because I can compile 3.3.2 (but it don't work with java)
The compilation problem is only with cvs version.
There can be something wrong, I'll try other computer, which is upgraded
to 9 from RedHat 8.

No, if I compile gcc 3.3.2 by command
make CFLAGS='-O2' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2
-fno-implicit-templates' bootstrap 
HelloWorld works well but if I use
make CFLAGS='-O3 -march=i686 -mcpu=pentium4' LIBCFLAGS='-g -O3
-march=i686 -mcpu=pentium4' LIBCXXFLAGS='-g -O3 -march=i686 
-mcpu=pentium4 -fno-implicit-templates' bootstrap
it failes to start.

cvs version failed to compile also other Redhat 9 machine.

What version of binutils do you have?
>From <http://gcc.gnu.org/install/specific.html#ix86-*-linux*>:
As of GCC 3.3, binutils 2.13.1 or later is required for this platform. See bug 10877 for more 
information.

Subject: Re:  SIGSEGV, Segmentation fault starting java program

RHL 9 ships with binutils 2.13.90 so I doubt this would be a problem.

Pekka, regarding your build problem, I build CVS GCC at least every few 
days on an RHL 9 system (and Im sure many others do), so the build 
error must have something to do with your environment or the commands 
you are using to build GCC.

FYI I build gcc using

cd cvs/gcc
mkdir build
cd build
../configure --prefix=/home/bryce/gcc --enable-languages=java 
--enable-java-awt=gtk --disable-static
make

The compiler you are using to build/bootstrap can also cause problems, 
make sure you are using redhat's compiler or a known-good GCC 3.3.x 
build in your path.
