When I run the fortran tests by themselves, it is okay, but in conjunction with the C and C++ tests, I see numerous failures.

The current behavior is inconsistent with the rest of the GCC user interface. And collect2 is losing the argument. So "-B" is consumed as the argument and the space-separated path argument to -B is interpreted as a separate file, which is not allowed with -c -o. Either -fintrinsic-modules-path needs to be modified to use "=" for its argument or collect2 needs to ignore that option completely because it is not relevant when compiling ctors. Thanks, David
