| ; wrong context. The definition of struct "HHH" is placed in the CU for 1.cpp. |
| ; While creating the template instance in "HHH", function "ccc" is referenced |
| ; via the struct local type, and "main" is created in the CU for 1.cpp, which |
| ; is incorrect. |
| ; |
| ; See PR48790 for more discussion and original compile commands. |
