             Bug #: 15204
           Summary: dwz causes addr2line to spew out errors
           Product: binutils
           Version: 2.23
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


I took a copy of libtcmalloc.so (r190, built unmodified from sources) and named
it orig.so.  I can do this with it:

$ addr2line -e orig.so 0x00000000000247b8
/home/luto/apps/gperftools/src/central_freelist.cc:283
$ cp orig.so dwz.so
$ dwz dwz.so 
$ addr2line -e dwz.so 0x00000000000247b8
BFD: Dwarf Error: Could not find abbrev number 91.
BFD: Dwarf Error: Could not find abbrev number 111.
BFD: Dwarf Error: Could not find abbrev number 91.
BFD: Dwarf Error: Offset (7632208) greater than or equal to .debug_str size
(281777).
BFD: Dwarf Error: Could not find abbrev number 101.
BFD: Dwarf Error: Could not find abbrev number 113.
<path>/gperftools/src/central_freelist.cc:283

orig.so and dwz.so are here: http://web.mit.edu/luto/www/binutils_bug/

My version of dwz is dwz-0.8-1.fc18.  I've tested this with
binutils-2.23.51.0.9 and F18's binutils.  I've also tried dwz 0.9 with similar
results.
