           Summary: unexpected symbol lookup error on Xilinx
                    implementation tools.
           Product: glibc
           Version: 2.14
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
        AssignedTo: drepper.fsp@gmail.com
        ReportedBy: pluto@agmk.net


Hi all,

i've found another problem with new glibc-2.14 and www.xilinx.com
implementation tools. for all my fpga projects at the end of processing
the xilinx mapper dies with following error:

(...long path...)/xilinx_13.1/ISE_DS/ISE/bin/lin64/unwrapped/map:
symbol lookup error: (...long
path...)/xilinx_13.1/ISE_DS/ISE//lib/lin64/libXst_Core.so: undefined symbol:
_ZN5antlr6BitSetD1Ev

i've checked dynamic deps and everything looks good.

_ZN5antlr6BitSetD1Ev export:

$ readelf -sW libAntlr.so|grep _ZN5antlr6BitSetD1Ev
   533: 0000000000018650    65 FUNC    GLOBAL DEFAULT   10 _ZN5antlr6BitSetD1Ev

_ZN5antlr6BitSetD1Ev import:

$ readelf -sW libXst_Core.so|grep _ZN5antlr6BitSetD1Ev
  6060: 0000000000000000    65 FUNC    GLOBAL DEFAULT  UND _ZN5antlr6BitSetD1Ev

and binding:

$ readelf -dW libXst_Core.so|grep Antlr
 0x0000000000000001 (NEEDED)             Shared library: [libAntlr.so]

on 2.13 it works fine. for 2.14 ugly workaround is LD_BIND_NOW=1.

looks like some kind of regression for 3rd-party binaries.
