Do you mean at exactly r193675 or at some point prior to that?

obviously not a libstdc++ bug in any case

This appeared between revisions 193417 (OK) and 193542 (UNRESOLVED) for serial
testing. I don't see it if I do a parallel testing (-j2).

> obviously not a libstdc++ bug in any case

I agree and I changed the component to testsuite. What it is strange is that
26_numerics/complex/abi_tag.cc is supposed to scan assembler (abi_tag.s), but
look at 20_util/enable_shared_from_this/cons/constexpr.cc.

Is there people around running the testsuite serially on non-darwin platform?

Does this mean that you have run a serial testsuite of libstdc++-v3 after
r193542 and you did not get the UNRESOLVED cases?

I suspect this issue existed from the original commit of...


r193445 | jason | 2012-11-12 12:51:26 -0500 (Mon, 12 Nov 2012) | 1 line

        * include/std/complex (real, imag): Add ABI tag in C++11 mode.

which introduced the 26_numerics/complex/abi_tag.cc testcase. This particular
commit is difficult to test on darwin because it occurred while the darwin
bootstrap was broken from the introduction of libsanitizer.

Note I saw this also for a cross to aarch64-linux-gnuwhen testing with an
already installed compiler on x86_64-linux-gnu. (I do almost all my testing on
an already installed compiler which allows to show bugs which we might not see
on the just built ones).
