           Summary: Internal Compiler Error
           Product: abc
           Version: 1.2.1
          Platform: PC
        OS/Version: Windows 2000
            Status: NEW
          Severity: major
          Priority: P2
         Component: AspectJ compiler
        AssignedTo: abc-bugs@comlab.ox.ac.uk

Compilation of an aspect into a java base causes the following dump:

        ... 2 more

to reproduce:

1. download ProGuard v3.7 from http://proguard.sourceforge.net/

2. unpack and add the file ObfuscateStats.aj to the src/proguard folder

package proguard;

public aspect ObfuscateStats {
        pointcut log(): call (* *.obfuscate(..));

        before(): log() {
                System.out.println("Entering obs");
        }
        
        after() returning: log() {
                System.out.println("Exiting Obs");
        }
}

3. from a command prompt in the src directory, create sourcelist with "dir /s /b
*.java *.aj > src.txt"

4. edit src.txt and remove any lines that refer to files with the ant directory
or the wtk directory

5. again from the src directory, execute "abc -argfile src.txt"

The same steps copleted successfully when using ajc 1.5.3
