FULL PRODUCT VERSION :
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)
FULL OS VERSION :
OSX 10.9.2
OSX 10.6.8
Ubuntu 14.04
Windows 7
A DESCRIPTION OF THE PROBLEM :
I have some simple code that causes a segmentation fault.
Running in the Eclipse debugger or with the interpreter (using -Xint option) prevents the segfault from occurring.
I made a stack overflow post here:
http://stackoverflow.com/questions/24101142/java-fatal-error-sigsegv
Several commenters, on several different machines, were able to reproduce the error.
My code involves cacheing some computations in logarithmic scale. Specifically, given log(X),log(Y),..., I have a small class that computes log(X+Y+...). And then I cache the result in a HashMap. My code is <100 lines long, and only uses classes from java.util (no native libraries).
THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: No
THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the small code I have attached.
Sometimes I have to run the code a couple of times for the error to occur, but it happens more often than not.
EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected: print out a bunch of numbers and terminate
Actual: print out a bunch of numbers and get a segmentation fault at some point.

CUSTOMER SUBMITTED WORKAROUND :
Rather than using an array to store all the log summands and then compute the logarithm of the sum in the most numerically stable way possible, I just store the sum and update it one number at a time (this is slightly less numerically stable).
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)
FULL OS VERSION :
OSX 10.9.2
OSX 10.6.8
Ubuntu 14.04
Windows 7
A DESCRIPTION OF THE PROBLEM :
I have some simple code that causes a segmentation fault.
Running in the Eclipse debugger or with the interpreter (using -Xint option) prevents the segfault from occurring.
I made a stack overflow post here:
http://stackoverflow.com/questions/24101142/java-fatal-error-sigsegv
Several commenters, on several different machines, were able to reproduce the error.
My code involves cacheing some computations in logarithmic scale. Specifically, given log(X),log(Y),..., I have a small class that computes log(X+Y+...). And then I cache the result in a HashMap. My code is <100 lines long, and only uses classes from java.util (no native libraries).
THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: No
THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the small code I have attached.
Sometimes I have to run the code a couple of times for the error to occur, but it happens more often than not.
EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected: print out a bunch of numbers and terminate
Actual: print out a bunch of numbers and get a segmentation fault at some point.

CUSTOMER SUBMITTED WORKAROUND :
Rather than using an array to store all the log summands and then compute the logarithm of the sum in the most numerically stable way possible, I just store the sum and update it one number at a time (this is slightly less numerically stable).
