llvm dev - Oct 2013 - [LLVMdev] ld: Assertion failed: (memberIndex != 0), function makeObjectFileForMember

Hi,

I'm encountering the following assertion when linking an Xcode project with
Xcode 4.6.3 (4H1503). The project has dependencies on, and links against, an
Objective-C static library Xcode project, and a C++ static library Xcode
project. All are using using LLVM 4.2.

ld: Assertion failed: (memberIndex != 0), function makeObjectFileForMember, file
/SourceCache/ld64/ld64-136/src/ld/parsers/archive_file.cpp, line 354.

0  0x10fa41098  __assert_rtn + 144
1  0x10fa678af 
archive::File<x86_64>::makeObjectFileForMember(archive::File<x86_64>::Entry
const*) const + 1149
2  0x10fa670fd

4  0x10fa80884  ld::tool::Resolver::resolve() + 44
5  0x10fa41380  main + 370
6  0x10fa32cd4  start + 52
A linker snapshot was created at:
	/tmp/<Name Removed>-2013-09-22-135411.ld-snapshot
ld: Assertion failed: (memberIndex != 0), function makeObjectFileForMember, file
/SourceCache/ld64/ld64-136/src/ld/parsers/archive_file.cpp, line 354.
clang: error: linker command failed with exit code 1 (use -v to see invocation)

The problem does not occur in Xcode 5.0 (5A1413) with LLVM 5, but unfortunately
I must continue to use Xcode 4 for a while.

Any suggestions for how to work around this assertion, or hints as to what is
going wrong would be greatly appreciated.

Thanks for reading.

Regards,
David

Hi David,

file /SourceCache/ld64/ld64-136/src/ld/parsers/archive_file.cpp, line 354.
This looks like a bug in the Apple linker, which isn't part of LLVM.
The best on-topic place to ask would probably be Apple's developer
forum (https://devforums.apple.com), but linkers are rather
specialised beasts.

The fact that it's been fixed in XCode 5 probably means filing a bug
won't be that useful for you. Having said that, the ld64 sources are
available online, so if you really need an XCode 4 solution you could
try to track it down yourself.

Sorry we couldn't be more help.

Tim.

Hi David,

I already saw this problem and it was due to a bad interaction (incompatible
versions) between cctools and ld, IIRC.

CC’ed Nick, he may have more information about that.

David,

This usually means a static library is corrupt.  The table of contents said a
symbol was in an object file at some offset in the archive, but the linker later
found there was no member at that offset.

Thanks to all of you for your help, and thanks for the explanation, Nick. This
will save me a lot of time, as now I know where to focus my efforts.
