It's reproducible with real hardware but not with qemu (on qemu one instead gets the expected bunch of error: undefined reference errors for objects not passed on the command line). Tests so far have been with 2.21.51.20110421-4 from Debian sid but presumably it shouldn't be hard to check with the latest from git://sources.redhat.com/git/binutils.git if that's useful. http://bugs.debian.org/616715 has details.

http://sourceware.org/bugzilla/show_bug.cgi?id=12771 --- Comment #7 from Jonathan Nieder jrnieder at gmail dot com 2011-06-29 15:35:40 UTC --- (In reply to comment #6) This seems far more likely to be a problem in the tools used to build gold, rather than a problem in gold itself. I'm going to close this out. Please reopen if you have some reason to believe that there is a problem in gold itself. Just for completeness: did you test on a non-emulated ARM system? The triggered failed assertion says bool found = object-merge_map()-get_output_offset(NULL, input_shndx, input_offset, output_offset); // If this assertion fails, it means that some relocation was // against a portion of an input merge section which we didn't map // to the output file and we didn't explicitly discard. We should // always map all portions of input merge sections. gold_assert(found); That doesn't immediately scream code generation bug to me --- it could be a use of uninitialized memory or some other portability problem. If I wanted to pin it on something other than gold this early, I'd be more likely to blame libstdc++ than the code generation, but it's hard to learn anything without hardware to investigate on. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils

Debian liblzma5 5.1.1alpha+20110809-3 does that. It provides two versions of the lzma_code function --- an unversioned compatibility symbol and a versioned symbol: | $ eu-readelf -s /usr/lib/x86_64-linux-gnu/liblzma.so.5.0.0 | grep lzma_code |32: 30f0142 FUNCGLOBAL DEFAULT 13 lzma_code |33: 3020202 FUNCGLOBAL DEFAULT 13 lzma_code@@XZ_5.0 When I link to the library using ld.bfd, the versioned symbol is preferred, as I'd expect[2]: | $ ld.bfd -o test.bfd test.o -llzma | ld.bfd: warning: cannot find entry symbol _start; defaulting to 00400270 | $ eu-readelf -s test.bfd | grep lzma_code | 1: 0 FUNCGLOBAL DEFAULTUNDEF lzma_code@XZ_5.0 (2) |17: 0 FUNCGLOBAL DEFAULTUNDEF lzma_code@@XZ_5.0 By contrast, ld.gold seems to prefer the unversioned symbol. | $ ld.gold -o test.gold test.o -llzma | $ eu-readelf -s test.gold | grep lzma_code | 1: 0 FUNCGLOBAL DEFAULTUNDEF lzma_code | 5: 0 FUNCGLOBAL DEFAULTUNDEF lzma_code Reproducible with binutils 2.22 and with a current snapshot of HEAD (3d38152c, 2011-12-19). Known problem? Any hints for tracking it down? [1] “The second GNU extension is to allow multiple versions of the same function to appear in a given shared library. In this way you can make an incompatible change to an interface without increasing the major version number of the shared library, while still allowing applications linked against the old interface to continue to function. “To do this, you must use multiple `.symver' directives in the source file. Here is an example: __asm__(.symver original_foo,foo@); __asm__(.symver old_foo,foo@VERS_1.1); __asm__(.symver old_foo1,foo@VERS_1.2); __asm__(.symver new_foo,foo@@VERS_2.0); “In this example, `foo@' represents the symbol `foo' bound to the unspecified base version of the symbol. The source file that contains this example would define 4 C functions: `original_foo', `old_foo', `old_foo1', and `new_foo'.” [2] “When you have multiple definitions of a given symbol, there needs to be some way to specify a default version to which external references to this symbol will be bound. You can do this with the `foo@@VERS_2.0' type of `.symver' directive. You can only declare one version of a symbol as the default in this manner; otherwise you would effectively have multiple definitions of the same symbol.” -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
