[Bug java/20773] New: ICE: SEGV building jar file

[green at redhat dot com]

I'm seeing the following:

# gcj -O2 -shared -findirect-dispatch -Wl,-Bsymbolic -fPIC -o libtritonus.jar.so
tritonus.jar 
org/tritonus/util/TCircularBuffer.java: In class
'org.tritonus.util.TCircularBuffer':
org/tritonus/util/TCircularBuffer.java: In method
'org.tritonus.util.TCircularBuffer.read(byte[],int,int)':
org/tritonus/util/TCircularBuffer.java:0: internal compiler error: Segmentation
fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla> for instructions.

This works at -O0 and fails at -O1 and above.

I will attach the jar file to this case.  It comes from tritonus-0.3.0 which is
Free Software.

Hmm, do you know what compiler the class files were created with?
I tried building tritonus's org/tritonus/share/TCircularBuffer.java to a class with both Apple's javac and 
gcj and I had no luck reproducing it.  (This is only for a semi self contained testcase).

This is either a bug in tree-cfg.c or tree-ssa-loop-ch.c, I cannot figure out which one.

Should have been marked as a regression.

On the mainline we get:

Fixed on the mainline, I think the 4.0 branch's bug is slightly different also.
