What settings in cesm are changed when I set "DEBUG=TRUE" in env_build.xml? I got a run error but ran successfully in debug-mode

Dear all

I got a running error when I ran cesm1_0_4 with pgi10.6 and openmpi3.1.0.  Here's the error message in the ccsm.log.

However, when I set the ‘DEBUG=TRUE’ in the env_build.xml, the model ran successfully.

Here are my quesitions.

(1) What settings in cesm are changed when I set "DEBUG=TRUE" in env_build.xml?

(2) How can I run the model without running error when I turn off the DEBUG in the env_build.xml?

Thanks in advance

May F
