Cape Verde).

I suspect symbol_count might be 0 in parse_symbol_table(), in which case
binary->global_symbol_offsets would probably end up as NULL.

Not sure that should ever happen though. Michael, which version of libelf are
you using?

Can you run the program with CLOVER_DEBUG=clc,llvm,asm and post the output.

OK, I guess, I identified the issue.

ImageMagick cached an old OpenCL program compiled some months ago, after
removing that, it does not crash any more.

Now the build fails, because cospi() and sinpi() are not yet supported by
libclc.

Should be fixed by:

commit 60b42171139886edb8a64624e9126eab36f8e726
Author: Aaron Watry <awatry@gmail.com>
Date:   Thu Feb 26 15:42:00 2015 +0000

    libclc/math: Add cospi

    Ported from the libclc/amd-builtins branch

    v2: Rename sincos_f_piby4 to __libclc__sincosf_piby4
        Add cospi(double) implementation instead of using llvm.cos

    Notes:
    The sincosD_piby4.h file is mostly the same as the builtin implementation
    released by AMD. The inline attribute declaration is changed, and M_PI is
    used instead of a constant double. Otherwise, the only difference is that
    the header explicitly enables the fp64 pragma.
