[Bug java/13948] New: GCJ segmentation fault while compiling GL4Java .class files

[gilead at yellowhedgehog dot com]

When trying to compile GL4Java project .class files into native code GCJ crashes.

I prepared minimal test case.

Command I issue and its result:

I can reproduce this.  The command line which I can reproduce this with:
gcj -o libgl4java.so gl4java/GL4JavaInitException.class gl4java/GLRunnable.class
Note you have include "-o filename" part else it will not seg fault.

Yet another Miranda methods bug!

FWIW, for me it happens *only* if I say:

gcj -shared -o libgl4java.so gl4java/GL4JavaInitException.class
gl4java/GLRunnable.class

It *does not happen* if I:

  1. Omit the "-o" flag (as Andrew Pinski points out).
  2. Use Java sources instead of class files.
  3. Reverse the order of the classes on the command line.

Are you using the latest CVS sources? Bryce also fixed a couple of class
loading bugs recently (after the fix above went in). If the problem still
persists, can you at least give the backtrace with a "debug_tree()" of
the class that is causing problems?

I can build the rhug ant just fine with current cvs head.
I'm closing this; I'll ping Anthony to see if he still has problems.
