Bug ID: 28496
Summary: clang crashes on likely invalid C++11 code: Assertion
`hasInClassInitializer() && InitStorage.getPointer()
== nullptr && "bit width, initializer or captured type
already set"' failed
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: unassignedclangb...@nondot.org
Reporter: s...@cs.ucdavis.edu
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
Classification: Unclassified
The current clang trunk crashes when compiling the following C++11 test case on
x86_64-linux-gnu in both 32-bit and 64-bit modes.
It also crashes 3.6.x and later and is rejected by 3.5.x and earlier.
It is
- rejected by GCC 6.x and later (5.x ICEs)
- accepted by GCC 4.8.x and 4.9.x
- accepted by MSVC 19.00.23720.0 (x86)
- rejected by ICC 13.0.1 (data member initializer unsupported)
Crash log is too large and thus omitted.
