Given two or more modules that import each other's scope, the current symbol lookup routines would go round in circles looking through each import from each module, possibly checking the same module twice or more until all possible paths are marked as "searched". Given enough modules, this causes an exponential slowdown in time taken to find symbols that do exist, and infinite recursion when they don't. gdb/ChangeLog: * d-namespace.c (d_lookup_symbol_imports): Avoid recursive lookups from cyclic imports. gdb/testsuite/ChangeLog: * gdb.dlang/circular.c: New file. * gdb.dlang/circular.exp: New file.
