Looks similar to <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - Assertion failed: !A->getDeducedType().isNull() && "cannot request the size of an undeduced or dependent auto type", file llvm\tools\clang\lib\AST\ASTContext.cpp, line 1884"
href="show_bug.cgi?id=31783">bug #31783</a>, but that is supposed to be fixed while the bug
above happens on trunk. Same with <a class="bz_bug_link
