Public bug reported:
A simple numerical calculation reliably leads to a JVM crash. This is on
Kubuntu 11.10 and java version "1.6.0_23", OpenJDK Runtime Environment
(IcedTea6 1.11pre) (6b23~pre11-0ubuntu1.11.10.2), OpenJDK 64-Bit Server
VM (build 20.0-b11, mixed mode).
Changing various, seemingly superficial aspects of the test case makes
the crash go away so it appears to be due to just the right combination
of factors . For example, changing the ternary operator in the test case
"denom != 0 ? num / denom : 0" to just "num / denom" eliminates the
crash.
I have attached a self-contained test case - to run, pass the
"crash"file to Java's standard input. This bug occurs every time I run
the test case. I have also attached a crash report. Please let me know
if there's any other information I should provide.
