Bug #: 15068
Summary: -Wdocumentation assert with empty @param paragraph
followed immediately by @param
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: Frontend
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
Reproduced on 3.2 release and on recent trunk (173180):
$ cat test.c
/**
@param x
@param y
**/
int f();
$ clang test.c -Wdocumentation
test.c:3:8: warning: empty paragraph passed to '\param' command
[-Wdocumentation]
@param y
~~~~~~~^
clang: /srv/users/ptaylor/clang/svn/llvm/include/llvm/Support/Casting.h:208:
typename llvm::cast_retty<To, From>::ret_type llvm::cast(const Y&) [with X =
clang::comments::ParagraphComment, Y = clang::comments::BlockContentComment*]:
Assertion `isa<X>(Val) && "cast<Ty>() argument of incompatible type!"' failed.
Adding anything (e.g. a space character) before the "@param y" appears to stop
the assertion failure.
