I am trying to build clang using the test-release.sh script https://github.com/llvm/llvm-project/blob/main/llvm/utils/release/test-release.sh , this was successful on clang 17.0.6 (with some file differences between phase 2 and 3). but no test failures, and check-all passed.
running as
```
./test-release.sh -j 5 -release $VERSION -use-ninja -final -triple x86_64-linux-gnu
```
however when doing the 18.1.8 version (or any of the 18 versions) it fails in the following test
https://github.com/llvm/llvm-project/blob/main/lldb/test/Shell/SymbolFile/DWARF/x86/debug-types-dwo-cross-reference.cpp
```

The lldb version seems to be breaking the tests, if i use the old lldb it seems to work as expected.
eg.
running the same command
```
lldb --no-lldbinit -S /git/llvm-project/llvm/utils/release/final/Phase3/Release/llvmCore-18.1.0-final.obj/tools/lldb/test/Shell/lit-lldb-init-quiet /git/llvm-project/llvm/utils/release/final/Phase3/Release/llvmCore-18.1.0-final.obj/tools/lldb/test/Shell/SymbolFile/DWARF/x86/Output/debug-types-dwo-cross-reference.cpp.tmp -o "target var a b **b.a"
```
with the old version
```

note: the same variables exist, i think its just that the older version is more lax on the rules and just prints the _expression_, whereas the new version only looks for global variables that actually exist
