[Bug gold/10098] New: gold 2.19.1: internal error in map_to_kept_section

gold aborts while linking a large C++ program with debug info. If the same
program is compiled without debug info the final link goes through OK.

I'm not sure if this is important: a small part of the code is
pre-compiled/pre-linked with another version of GCC that doesn't use gold.

My problem sounds similar to the following post on the binutils mailing list:


Here is the gdb backtrace (binutils compiled with -O0):

(gdb) cont

    this=0xaba71d0, shndx=69, found=0xbffe1bc3)                   
    at ../../binutils-2.19.1/gold/object.cc:1587                  
1587          gold_assert(os != NULL && offset != -1U);           
$3 = (class gold::Output_section *) 0x0                           
$4 = 4294967295                                                   

(gdb) l
1582        {
1583          gold_assert(kept->object_ != NULL);
1584          *found = true;
1585          Output_section* os = kept->object_->output_section(kept->shndx_);
1586          Address offset =
1587          gold_assert(os != NULL && offset != -1U);
1588          return os->address() + offset;
1589        }
1590      *found = false;
1591      return 0;
