[OMNI] OMNI Compiler compilation failed with some compilers (Apple LLVM)

[clementval]

The produced executable is not behaving the same when OMNI Compiler is compiled with GCC or with another compiler like Apple LLVM.

With the following compiler:

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 8.1.0 (clang-802.0.41)
Target: x86_64-apple-darwin16.5.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

We get the following error during the build:

./F_Front -module-compile fincludes/iso_c_binding.f90 > fincludes/iso_c_binding.xmod
/bin/sh: line 1: 95551 Abort trap: 6           ./F_Front -module-compile fincludes/iso_c_binding.f90 > fincludes/iso_c_binding.xmod
