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 \

Confirmed, looks like someone forgot to check for an NULL before passing to strlen.
Here is the backtrace on the mainline:
#1 0x0804bba4 in yyparse () at parse-scan.y:517
517 char *n = xmalloc (bracket_count + 1 + strlen ($$));
(gdb) bt
#0 0x42080bbb in strlen () from /lib/i686/libc.so.6
#1 0x0804bba4 in yyparse () at parse-scan.y:517
#2 0x0804bf91 in main (argc=3, argv=0xbffec3a4) at /home/gates/pinskia/src/gnu/gcc/src/gcc/

The patch causes jv-scan.c to fail to built when --enable-mapped-location.
You can no longer assign to input_filename and input_line individually.
(There are other --enable-mapped-location build failures, which I'm working on.)
Wasn't there talk about removing jv-scan?

gcc/java : parse-scan.y lex.c jv-scan.c ChangeLog
Log message:
PR java/15543
* parse-scan.y (input_location): Remove variable.
(main_input_filename): New - replaces input_filename, which isn't
settable if USE_MAPPED_LOCATION.
* lex.c (java_init_lex): Wrap some more places in #ifndef JC1-LITE,
so we don't reference input_location or wfl_operator in that case.
* jv-scan.c (expand_location): Remove - no longer used.
(main): Set main_input_filename rather than input_filename.
