failure-inducing testcase
Weird-- I get the various errors below if I repeatedly run this compile
command:
clang -Os small.c -c
clang: TargetData.cpp:446: uint64_t llvm::TargetData::getTypeSizeInBits(const
llvm::Type*) const: Assertion `Ty->isSized() && "Cannot getTypeInfo() on a type
that is unsized!"' failed.
clang: /home/regehr/z/compiler-build/llvm-r108290/include/llvm/User.h:104:
llvm::Value* llvm::User::getOperand(unsigned int) const: Assertion `i <
NumOperands && "getOperand() out of range!"' failed.
Sometimes I get neither error message! But it always crashes.
