. in Tomcat 7.0.16 (the latest at this date)
. many libraries

REGRESSION.  Last worked in version 6u26

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I couldn't create a simple unit test that crashes (trust me I tried),
but it always happens at the end of my server init, when I use the jregex library. It's the compiler that crashes.
The crash log gives me:

EVALUATION Very rare case when CMoveP control edge is CountedLoop back control. During loop iteration splitting CMoveP clone is placed on entry path of post-loop. Later when pre-loop is created clone_loop() code pulls Bool and Cmp nodes through Phi down to CMoveP clone. Note that Phi's region is above CMoveP clone's control which is fallthrough path of post-loop's zero-trip guard. Split through Phi optimization tries to reverse this merged subgraph and incorrectly splits this CMoveP node. As result 2 clones of CMoveP were placed at the same place as original node. It creates bad graph. The fix itself is very small: don't split CMove node if it's control edge is different from split region. Large part of changes is additional debug output in build_loop_late_post() where bad graph is detected. It helped me investigate this problem.

EVALUATION The submitter reported that the problem still occurs when using 7u2. An hs_err file is attached.
30-12-2011
EVALUATION This problem is likely caused by one of a few loop optimization bugs which have been fixed in JDK 7u1. Changing the status to "Incomplete" while waiting for verification that this problem is fixed in JDK 7u1, which is available at http://www.oracle.com/technetwork/java/javase/downloads/index.html
