I successfully compiled and produced the Linux version of the SWAT+ executable (v61.0.2.11) using the source code from github.

However, running "ctest" (which makes sure the SWAT+ executable is correct) produces the following error:

Test project /home/mirajbk/SWATplus/swatplus/build
Start 1: Ames_sub1
less 1/1 Test #1: Ames_sub1 ........................***Failed 1.95 sec

0% tests passed, 1 tests failed out of 1

Total Test time (real) = 1.97 sec

The following tests FAILED:
1 - Ames_sub1 (Failed)
Errors while running CTest

Looking at the log, I got the following error:

Program received signal SIGFPE: Floating-point exception - erroneous arithmetic operation.

Backtrace for this error:

I found that the error occurs on days with high precipitation. Has anyone encountered this problem? Any help is appreciated.
