Hi,
Just tried trunk and its still broken wrt. __is_constructible
The reduced test case doesn't include uses of __is_constructable or any
other type trait primitive.
I can confirm though that it does crash somewhere in parameter pack
handling, which is used to pass types to the built-in:
Assertion failed: (Replacement.isCanonical() && "replacement types must
always be canonical"), function getSubstTemplateTypeParmType, file
/Users/alp/Projects/llvm-work/upstream/clang/lib/AST/ASTContext.cpp,

Hi,
Attached is a testcase with unrelated errors in it. I am still
trying to reduce a non-error version but if this one works cool.
Get latest libcxx and compile with clang++ -std=c++11 -c testcase.ii

Any chance you could produce a reduced testcase and file a bug
against Clang? =)

New Revision: 206805
URL:
http://llvm.org/viewvc/llvm-project?rev=206805&view=rev
Log:
Use compiler intrinsic __is_constructible if
available
Modified:
libcxx/trunk/include/type_traits
This breaks the llvm compilation (in stage2 hence
clang is the compiler here) for me on Linux/x86-64:
Sorry; was in meetings all day yesterday.
Looks like a bug in the __is_constructible code in clang.
As a workaround (and a check to make sure that’s what
it is), would you please change (in type_traits)
#if __has_feature(is_constructible)
to
#if 0
and let me know if that fixes the crash?
This indeed fixes the crash.
Regards.
