Double free or corruption error in greedy_projection

[zachbogorad]

Environment

• Operating System and version: Ubuntu 16.04
• Compiler: gcc 5.4.0
• PCL Version: 1.8.0
• Eigen Version: 3.3

Expected Behavior

I'm trying to get the greedy_projection example provided and described here to work. I'm running it on the example input file listed there ("bun0.pcd"). I'm not actually sure what the output for that should look like, but at the moment I get no output anyway so it doesn't matter.

Current Behavior

Everything compiles fine as far as I can tell, but when I try to run the binary, I get a double free or corruption error. A gdb backtrace gives:

I know the example has worked for at least one colleague and I'm not sure what the difference is that's causing it not to work for me. I'll be happy to provide other details about my installation, I just don't know what else is needed.

Sorry for the late reply. I have the impression that your problem might be closely related to #2013, and the reason behind it is #2013 (comment). Can you apply the following patch #2100 and report the results?

Basically you just need to make sure that the same SSE flags that were used to compile PCL are being used to compile the application which is linking against PCL.

This one is probably fixed now. Closing.
