You're absolutely right: enums are not generating any test for validity. I would expect to see a C_i_foreign_integer_argumentp test there. I don't know if this behaviour is intentional.
You could try this patch to Chicken, which adds a test for integer. (Patch is against darcs HEAD but probably applicable to earlier.) On 7/1/07, Ivan Raikov <[EMAIL PROTECTED]> wrote:
I accidentally discovered that the procedure blas:dgemm in the blas egg causes a segmentation fault when called with a TRANSPOSE argument that is a character, instead of one of the transpose constants. Is this normal, or could it possibly be an indication of an issue with the FFI interface?
