            Bug ID: 26385
           Summary: Cannot re-direct llvm-config output to file when
                    configuring with LLVM_LINK_TOOLS_DYLIB
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Support Libraries
          Assignee: unassignedbugs at nondot.org
          Reporter: tstellar at gmail.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

It appears that the destructor for outs(), which llvm-config uses to print
output, is never called so the output is never flushed.  This only seems to
happen when using -DLLVM_LINK_TOOLS_DYLIB

This makes it impossible to redirect output from llvm-config to a file:

llvm-config --version > llvm-version.txt

Results in an empty file.
