[Bug libgcj/28979] New: GCJ errors out when compiling .class files produced by Scala 2.1.8

[vnasardinov at gmail dot com]

I'm getting an error when trying to compile the following classes with
gcj:

 | $ scalac hamming.scala 
 | $ ls -lh *.class
 | -rw-rw-r-- 1 vadim vadim 1.1K Sep  7 20:16 hamming$$anonfun$0.class
 | -rw-rw-r-- 1 vadim vadim 1.1K Sep  7 20:16 hamming$$anonfun$1.class
 | -rw-rw-r-- 1 vadim vadim 1.1K Sep  7 20:16 hamming$$anonfun$2.class

 | $ jar cf hamming.jar *.class

The .class files were produced by Scala 2.1.8:
  http://scala.epfl.ch/downloads/distrib/files/scala-2.1.8.tar.gz

The above is under the following version of GCJ:

 | $ gcj -v
 | Using built-in specs.
 | Reading specs from /usr/lib/gcc/x86_64-redhat-linux/4.1.1/libgcj.spec

 |   --infodir=/usr/share/info --enable-shared --enable-threads=posix \
 |   --enable-checking=release --with-system-zlib --enable-__cxa_atexit \
 |   --disable-libunwind-exceptions --enable-libgcj-multifile \
 |   --enable-languages=c,c++,objc,obj-c++,java,fortran,ada \
 |   --enable-java-awt=gtk --disable-dssi \
 |   --with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre \
 |   --with-cpu=generic --host=x86_64-redhat-linux
 | Thread model: posix
 | gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)

I will attach the offending .jar file in a minute.

I bet this was fixed in 4.2.0 with the ABI changing patch which changed the ABI
to also include the return type.

PR 28892 reminded me that I had forgotten to mention one thing.  The
attached program (attachment 12208) runs fine under gij.

To be more precise, it does more or less the same thing it does under
Sun's JDK.  Under Sun:

 | $ time java \
 |   -classpath /usr/local/scala/share/scala/lib/scala-library.jar:hamming.jar
\
 |   hamming
 | The first 20 numbers:
 | 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 25, 27, 30, 32, 36
 | 
 | The 100th number (counting from 0): 1600
 | 
 | The 1000th:
 | Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
 | 
 | real 0m9.922s
 | user 0m6.532s
 | sys  0m2.780s


Under gij:

 | $ gij \
 |  --classpath /usr/local/scala/share/scala/lib/scala-library.jar:hamming.jar
\
 |  hamming
 | The first 20 numbers:
 | 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 25, 27, 30, 32, 36
 | 
 | The 100th number (counting from 0): 1600
 | 
 | The 1000th:
 | Killed

Under Sun, it causes an OOM when trying to compute the 1000th Hamming
number.  Under gij, it starts paging like there is no tomorrow, but
keeps on going and hoses up my machine pretty quickly.

This is fixed in svn head.  Part was fixed by the mangling change,
which we can't backport to 4.1.  The other part was fixed when
the PR 28892 fix went in today.

I didn't let it try to compute the 1000th number but the rest worked.
