This fixes ICEs where unattached lambdas at class scope (for instance, in member template instantiations) are streamed. 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.
