the code that makes gold abort
At first I want to apologize for the huge minimal-example with
boost-dependency, but I have not been able to reduce it any further. Removing
any line I tried resulted in the bug disappearing.
If I try to compile the attached code, clang (or to be precise: gold) aborts
with the following error-message during linking:
atomic store operand must be power-of-two byte-sized integer
store atomic i1 true, i1* @_ZL11debug_level.0 seq_cst, align 1
i1Broken module found, compilation aborted!
Stack dump:
0. Running pass 'Function Pass Manager' on module 'ld-temp.o'.
1. Running pass 'Module Verifier' on function '@main'
clang: error: unable to execute command: Aborted (core dumped)
clang: error: linker command failed due to signal (use -v to see invocation)
make: *** [a.out] Fehler 254
This could be produced on two completely independent systems (Archlinux x86_64
and Fedora).</pre>
