Default BFAST malloc error

Hi,

I am getting the below memory corruption error when trying to run BFAST on a 4GB RAM machine.

Could you please advise?

Thanks.

Could you try to find a small test case so we can debug, or run it in gdb and identify the line in the source code? Tell us your environment and other variables.
