 |-----------
 ||-O0          ||Reduce compilation time and make debugging produce the expected results.  ||
+||-ffpe-trap=  ||Specifies a list of IEEE exceptions when a Floating Point Execption (FPE) should be raised. ''invalid'': invalid floating point operation, such as SQRT(-1.0), ''zero'': division by zero, ''overflow'': overflow in a floating point operation. ||
 ||-Wall        ||Enables commonly used warning options pertaining to usage that we recommend avoiding and that we believe are easy to avoid. This currently includes -Waliasing, -Wampersand, -Wsurprising, -Wintrinsics-std, -Wno-tabs, -Wintrinsic-shadow and -Wline-truncation.  ||
 ||-Wextra      ||Enables some warning options for usages of language features which may be problematic. This currently includes -Wcompare-reals and -Wunused-parameter.  ||
 ||-pedantic    ||Issue warnings for uses of extensions to Fortran 95.  ||
-||-fcheck=all  ||Enable all run-time test of -fcheck.  ||
+||-fcheck=all  ||Enable all run-time tests of -fcheck.  ||
 ||-fbacktrace  ||Specify that, when a runtime error is encountered or a deadly signal is emitted (segmentation fault, illegal instruction, bus error or floating-point exception), the Fortran runtime library should output a backtrace of the error.  ||
