Okay. I'll note that flang is new to devel/llvm13 and, for comparison to historical build-clang memory use, I ignore flang. Building flag is not involved in buildworld. But the failures that you have reported were not building clang or anything from the llvm project. They were building gmock things. An interesting thing that I've noted in your reporting: c++: note: diagnostic msg: /tmp/gmock-all-836ef8.cpp c++: note: diagnostic msg: /tmp/gmock-all-836ef8.sh vs. http://www.zefox.net/~fbsd/rpi3/20220121/ which has: =E2=80=A2 gmock_main-f5c28a.cpp =E2=80=A2 gmock_main-f5c28a.sh Those are different .cpp files and I only have access to the gmock_main-f5c28a.cpp related pair of files. I've never gotten a failure for what I have access to. You have not reported the lldb result for my reply that listed doing: QUOTE To look at the different frames: (lldb) up 1 (lldb) bt . . . (output) . . . (lldb) up 1 (lldb) bt . . . (output) . . . and so on until #5 has been displayed. END QUOTE This was a gmock_main-f5c28a.cpp context. The "up" commands make the sequence more than just "repeated bt commands". It should show the source code of the lines of code in question for the specific frame, much like it did for frame #0 in what you had sent to the list. =20 =3D=3D=3D Mark Millard marklmi at yahoo.com
