Test case
Note: This sounds really similar to <a class="bz_bug_link
bz_status_RESOLVED bz_closed" title="RESOLVED FIXED - generic lambda capture fails with undefined reference to custom copy ctor" href="show_bug.cgi?id=22354">bug 22354</a>, but it's still present in 3.6.
Compiling the attached test case under clang 3.6 succeeds, but *fails* during
linking:
$ clang++-3.6 -std=c++1y test.cpp
/tmp/test-1c245e.o: In function `see_the_animals()':
test.cpp:(.text+0x1a): undefined reference to `zoo::zoo(zoo const&)'
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
Here's my clang version (it should be from the LLVM apt repo):
Ubuntu clang version 3.6.0-2ubuntu1~trusty1 (tags/RELEASE_360/final) (based
on LLVM 3.6.0)
Target: x86_64-pc-linux-gnu
Thread model: posix</pre>
