Building perf fails with gold:

markus@x4 perf % pwd
markus@x4 perf % gcc -c annotate.i -O2 -g3
line-map.c: file "/usr/include/glib-2.0/gio/gbufferedinputstream.h" left but not entered
line-map.c: file "/usr/include/glib-2.0/gio/gfilteroutputstream.h" left but not entered
line-map.c: file "/usr/include/glib-2.0/gio/gcharsetconverter.h" left but not entered
markus@x4 perf % ld -r -o /dev/null annotate.o
ld: error: annotate.o: could not decompress section .debug_str

ld.bfd is fine.

I have tried to reduce the testcase, but the failure then depends
on the directory in which gcc is invoked.

commit 9706b5e627dfae1ab0a2788dda8a2aa5a0e09af7

    Change ch_type to Elf_Word in struct Chdr_data<64>
    The ch_type field in struct Chdr_data<64>  is 4 bytes, followed by a
    4-byte padding.  This change doesn't introduce any functional change
    since only the lower 32 bits of the ch_type field are used.
    	PR gold/19060
    	* elfcpp.h (Chdr::get_ch_type): Change return type to Elf_Word.
    	* elfcpp_internal.h (Chdr_data<64>): Change ch_type to 4 bytes
    	and add ch_reserved.
