            Bug ID: 24491
           Summary: Regression(r243752): check-all is broken if libcxxabi
                    is checked out
           Product: libc++abi
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedbugs at nondot.org
          Reporter: nicolasweber at gmx.de
                CC: llvm-bugs at lists.llvm.org, mclow.lists at gmail.com
    Classification: Unclassified

On OS X, self-built clang can't find headers unless `-isysroot $(xcrun
-show-sdk-path)` is passed. Hence, from r243752 on, all libcxxabi tests fail
with errors like:

FAIL: libc++abi :: backtrace_test.pass.cpp (27888 of 27933)
