[Bug java/15543] New: "jv-scan --complexity" segfaults

[vadimn at redhat dot com]

I came across two .java files that cause jv-scan to segfault.  The files
are

http://cvs.forge.objectweb.org/cgi-bin/viewcvs.cgi/*checkout*/speedo/src/org/objectweb/speedo/generation/enhancer/CodeDuplicator.java?rev=1.6&content-type=text/plain
http://cvs.forge.objectweb.org/cgi-bin/viewcvs.cgi/*checkout*/speedo/src/org/objectweb/speedo/generation/enhancer/ClassAccessorModifier.java?rev=1.31&content-type=text/plain

Here's what I get:

$ jv-scan --complexity \
 src/org/objectweb/speedo/generation/enhancer/CodeDuplicator.java
Segmentation fault
$ jv-scan34 --complexity \
 src/org/objectweb/speedo/generation/enhancer/CodeDuplicator.java
Segmentation fault

Build information for jv-scan is as follows:

$ rpm -ql $(rpm -qf $(which jv-scan)) | grep /bin
