Failure when using profile guided optimizations on OSX

[meldaproduction]

 For the I tried to use profile guided optimizations and after about an hour of compiling (it's a big project), this is what I got:

0  0x10da73b51  __assert_rtn + 144
1  0x10dad99fb  ld::tool::OutputFile::addressOf(ld::Internal const&, ld::Fixup const*, ld::Atom const**) + 155
2  0x10dadafaf  ld::tool::OutputFile::applyFixUps(ld::Internal&, unsigned long long, ld::Atom const*, unsigned char*) + 1663
3  0x10dae03a5  ld::tool::OutputFile::writeAtoms(ld::Internal&, unsigned char*) + 495
4  0x10dad8e4f  ld::tool::OutputFile::writeOutputFile(ld::Internal&) + 779
5  0x10dad3551  ld::tool::OutputFile::write(ld::Internal&) + 149
6  0x10da7481a  main + 1028
A linker snapshot was created at:
/tmp/libMeldaProductionAudioPluginKernel.dylib-2015-03-15-174847.ld-snapshot
ld: Assertion failed: (_mode == modeFinalAddress), function finalAddress, file /SourceCache/ld64/ld64-241.9/src/ld/ld.hpp, line 731.

For the record, on Windows it works, but the build for generating profile guided database doesn't work 100%, but in most cases it does...

Hello meldaproduction,

I can't reproduce using -prof-gen and -prof-use with the vec_samples with 15.0 initial product on OS X. I did some googling of that linker assertion, but nothing jumped out at me as being particularly useful. I have a couple questions which should help reproduce and/or identify the problem:

1. What version of OS X* and Xcode* are you using?

2. What specific version of the Intel(R) C++ Compiler are you using? (Adding -V to the compiler command line should give this information)

3. What compiler and linker options are you using when you get the linker crash?

Thanks. I'm using newest OSX, newest XCode and newest ICC. Here are the command lines:
