Bug ID: 15831
Summary: Python bindings don't report errors in get_size
Product: new-bugs
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P

Classification: Unclassified
In plain libclang, the clang_Type_getSizeOf function returns either a size or a
negative enum value taken from CXTypeLayoutError. The Python wrapper, get_size,
simply casts the value to an unsigned 64-bit integer. This means that if
get_size is called for a variable whose size isn't known (e.g. a
variable-length array), then a very large number (0xffffffffffffffc, in the
case of a VLA) is returned instead of an error.
