            Bug ID: 23292
           Summary: llvm-symbolize can't demangle some function in libc++
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: dvyukov at google.com
                CC: llvmbugs at cs.uiuc.edu, mclow.lists at gmail.com
    Classification: Unclassified

clang version 3.7.0 (trunk 235290)
Target: x86_64-unknown-linux-gnu

Testing reproducer from https://llvm.org/bugs/show_bug.cgi?id=23235 with
tsan-ified libc++ I got the following output:

    #0
_ZNSt3__18__invokeIMNS_19__async_assoc_stateIbNS_12__async_funcIZ4mainE3$_0JEEEEEFvvEPS5_JEvEEDTcldsdeclsr3std3__1E7forwardIT0_Efp0_Efp_spclsr3std3__1E7forwardIT1_Efp1_EEEOT_OS9_DpOSA_
include/c++/v1/__functional_base:382:43 (a.out+0x000000499458)

The function is not demangled while all other function are demangled.
This looks like a bug in demangler.
