Bug ID: 30538
Summary: Assertion `!T->isDependentType() && "should not see
dependent types here"' failed.
Product: clang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: mcros...@codeaurora.org
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
Classification: Unclassified
CReduced test case:
template <class, unsigned, unsigned> class BF32;
template <template <class, unsigned M, unsigned = M> class BF>
class CRBase {
enum { BIT };
BF<bool, BIT> Bit;
};
CRBase<BF32> CR;
Compile with: clang -O3 test.cpp
Should result in the below assertion failure. However, gcc will report an
error and exit gracefully.
