Okay... I've seen this problem in the archives before, but have yet to
find a solution:
My system:
Red Hat Linux 6.0 on i686
Linux 2.2.13 (custom build)
libstdc++ 2.9.0-12
I know some of you will scream about this, but I'm a little pressed for
time, so I used the following RPMs from http://rpmfind.net:
binutils-2.9.1.0.25-5mdk.i586.rpm
gcc-java-2.95-4.i686.rpm
gcc-2.95-4.i686.rpm
gcc-libgcj-2.95-4.i686.rpm
gcc-c++-2.95-4.i686.rpm
cpp-2.95.1-3.i386.rpm (there was no RPM of cpp-2.95, might this cause
problems?)
========
My boilerplate program:
========
HelloWorld.java:
public class HelloWorld {
public static void main( String args[] ) {
System.out.println( "Hello world!" );
}
}
========
I run:
========
$ unset CLASSPATH
$ gcj -g --main=HelloWorld HelloWorld.java -o hello
$ ls -l hello
-rwxrwxr-x 1 alex alex 18554 Nov 10 13:28 hello
$ ./hello
Segmentation fault (core dumped)
========
Following earlier instructions from the list archives, I then run:
========
$gdb hello
[blah blah blah...]
(gdb) run
Starting program: /home/alex/dev/java/alex/hello

Look familiar? I don't even know where to begin.
TIA,
Alex.
