<pre>$ clang -v
clang version 7.0.0 (trunk 327009) (llvm/trunk 327036)
I'm getting many of these, which causes linking to fail.
`.text.sancov.module_ctor.14' referenced in section
`.init_array.2[sancov.module_ctor.14]' of
./.libs/libexample_util.a(example_util.o): defined in discarded section
`.text.sancov.module_ctor.14[sancov.module_ctor]' of
./.libs/libexample_util.a(example_util.o)
Now this is on Ubuntu 14.04 LTS with fairly old binutils.
$ ld -v
GNU ld (GNU Binutils for Ubuntu) 2.24
Updating to binutils of the latest LTS (16.04) doesn't work either, same error.
$ ld -v
GNU gold (GNU Binutils for Ubuntu 2.26.1) 1.11
Only an update to the latest version of the first non-LTS release (17.01) turns
the errors into warnings.
./.libs/libexample_util.a(example_util.o)(.init_array.2+0x0): warning:
relocation refers to discarded section
$ ld -v
GNU gold (GNU Binutils for Ubuntu 2.29.1) 1.14
I don't know what the policy is, but unless binutils isn't supported any more,
I think this classifies as a bug.
PS. lld works of course.</pre>
