  Additional Information - Compiler Issue

Testing indicates that some Fortran compilers on some platforms may not comply fully with the parenthesis integrity stipulations of the ANSI standard. This problem may manifest itself when running the Fortran test program t_sofa_f.for by reporting the failure of a particular routine, usually with a discrepancy of the order of 10^-13, which results in a "Validation failed" message. Rather than relaxing the standards of the testing process, we are bringing this finding to the attention of users of the SOFA Fortran Library. If you do experience this issue, please i) recompile both the test software and the library of routines without optimization (e.g. using options of the form -O0 rather than relying on the default state of optimization of the compiler) and try again and ii) contact the SOFA Board providing information on your compiler, operating system, hardware and which optimization options were set, if any, including those used by default.

This problem does not affect the ANSI C library.
