The code below incorrectly gives the error, as reported by Salvatore Filippone:
Call foo_pwrk(pr,p,f,cd,info,work=aux) 1 Error: There is no specific subroutine for the generic 'bar_pwrk' at (1) Not only does it look correct but other compilers handle it OK. module.c is not finding the "true name" symbol, even though it has been created with the "use name" symtree. A quick inspection of the .mod file reveals that the interface is given the true name, which simply is not findable by read_module.
