preprocessed C source from libiconv-1.14
Assertion failure:
clang-4.0: ~/llvm/latest/include/llvm/Support/Casting.h:237: typename
llvm::cast_retty<X, Y*>::ret_type llvm::cast(Y*) [with X =
clang::UnaryOperator; Y = const clang::Expr; typename llvm::cast_retty<X,
Y*>::ret_type = const clang::UnaryOperator*]: Assertion `isa<X>(Val) &&
"cast<Ty>() argument of incompatible type!"' failed.
...
...
1. ./iconv.c:401:42: current parser token ')'
2. ./iconv.c:251:1: parsing function body 'check_subst_formatstring'
3. ./iconv.c:251:1: in compound statement ('{}')
----------------
Reproducer attached, occurs with:
clang -c input.c -o input.o
Has been occurring with trunk for at least a few days, and still occurs on
trunk as of time of writing.
Let me know if you have any trouble reproducing or if there's anything more I
can do to help resolve this.</pre>
