Trace/BPT trap when running rake, gem, or jirb using Java 1.7 (mlvm)
--------------------------------------------------------------------
Key: JRUBY-4969
URL: http://jira.codehaus.org/browse/JRUBY-4969
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.6
Environment: MacOS X 10.6.4, JRuby master, Java 1.7 (mlvm)
Reporter: Stephen Bannasch
Assignee: Thomas E Enebo
Using Java 1.7 with mlvm patchsets applied JRuby generates 'Trace/BPT trap'
errors using rake, gem, or jirb commands. In addition a handful of the
benchmark tests also generate this error.
I am using a build of mlvm from July 26 however I haven't tried using rake or
gem with earlier versions of mlvm so this problem may or may not have been
around before now.

Determine whether or not we should do reverse lookup here.
$ jruby -S gem env
Trace/BPT trap
$ jruby -S gem list rails
Trace/BPT trap
$ jruby -S rake -T
Trace/BPT trap
$ jruby -S rake test:short
Trace/BPT trap
$ jirb
Trace/BPT trap
{code}
FYI: I put a tarball of the latest Mac OS X mlvm build I am using here
(fastdebug enabled):
http://www.concord.org/~sbannasch/mlvm/java-1.7.0-internal-2010_07_26.tar.gz
{code}
java -version
openjdk version "1.7.0-internal-fastdebug"
OpenJDK Runtime Environment (build
1.7.0-internal-fastdebug-stephen_2010_07_26_09_07-b00)
OpenJDK Server VM (build 19.0-b03-fastdebug, mixed mode)
{code}
I also noticed that running these benchmarks in Java 1.7 (mlvm) also generated
Trace/BPT Trap errors:
