Bug ID: 50861
Summary: libstdc++ tests fail with GCC as the test compiler
Product: lldb
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: lldb-dev at lists.llvm.org
Reporter: teemperor at gmail.com
CC: jdevlieghere at apple.com, llvm-bugs at lists.llvm.org
All of these tests fail with GCC 8.5, 9.4, 10.3 and 11.1 as the test compiler.
Quick debugging suggests that we fail to ASTImport some type into the scratch
AST of LLDB.
Failure outputs:
```
FAIL: test_with_run_command_dwarf
(TestDataFormatterStdIterator.StdIteratorDataFormatterTestCase)
Test that libstdcpp iterators format properly.
