Repeatedly segfaulted the JVM when using the mysql gem
------------------------------------------------------
Key: JRUBY-6231
URL: https://jira.codehaus.org/browse/JRUBY-6231
Project: JRuby
Issue Type: Bug
Components: C Extensions
Affects Versions: JRuby 1.6.5
Environment: java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.4) (fedora-60.1.10.4.fc15-x86_64)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)
Reporter: Postmodern
Assignee: Thomas E Enebo
Attachments: hs_err_pid25574.log
When running benchmarks of the mysql gem (single-threaded vs. multi-threaded) I
was able to reliably Segfault the JVM. The Segfault appears to occur in the new
C-Extension JNI wrapping code.
