g++ compiled programs that link with Java Hotspot core dump

[Gerry McIntyre <mcintyrg at aol dot com>]

GCC guys,

I'm having a problem linking the Java HotSpot VM in with a g++ compiled
program.  Basically, any program (however simple) that gets linked with
the Java HotSpot VM (-ljvm) core dumps at initialization.  I've included
a quick example of the problem below:

warplan (47) % java -version
java version "1.3beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3beta-O)
Java(TM) HotSpot Client VM (build 1.3beta-O-release, 1.3beta-O-release,
interpreted mode)

warplan (48) % gcc -v
Reading specs from
/wsproj/users/lnmc/externals/GNU/lib/gcc-lib/sparc-sun-solaris2.6/2.95.2/specs

gcc version 2.95.2 19991024 (release)

warplan (49) % cat hello_world.cpp
#include <iostream>

main()
{
        std::cout << "hello world!" << std::endl;
}

warplan (50) % g++ hello_world.cpp

warplan (51) % a.out
hello world!

warplan (52) % g++ hello_world.cpp -ljvm

warplan (53) % a.out
Bus error (core dumped)

warplan (54) % gdb a.out

Any ideas?  I'm not a debugging guru, but it seems that the this is
occurring within the static initializer of the jvm library.  If that is
true, I'm not sure what you guys can do about it, but just thought I
would run it by you guys as well.  I'm also sending this to Sun.

Thanks,
Michael


BTW, why does iso646.h have "#ifndef __cplusplus"?  You want those
defines when you are compiling c++....???
