This is only possible in header units, as in named modules attempting to stream such lambdas will be an error. PR c++/116568 gcc/cp/ChangeLog: * module.cc (trees_out::get_merge_kind): Treat all lambdas without a mangling scope as un-mergeable. gcc/testsuite/ChangeLog: * g++.dg/modules/lambda-8.h: New test. * g++.dg/modules/lambda-8_a.H: New test. * g++.dg/modules/lambda-8_b.C: New test.
