[cfe-dev] Null CharacterLiteral Error

[dblaikie at gmail.com]

Works for Clang, so there must be something else going on in your program:

blaikie at blaikie:~/dev/scratch$ clang++-tot -Xclang -ast-dump ast.cpp -w

TranslationUnitDecl 0x5ec3190 <<invalid sloc>>

|-TypedefDecl 0x5ec36d0 <<invalid sloc>> __int128_t '__int128'

|-TypedefDecl 0x5ec3730 <<invalid sloc>> __uint128_t 'unsigned __int128'

|-TypedefDecl 0x5ec3af0 <<invalid sloc>> __builtin_va_list '__va_list_tag
[1]'

`-VarDecl 0x5ec3b80 <ast.cpp:1:1, col:13> ptr 'char *'

  `-ImplicitCastExpr 0x5f0b030 <col:13> 'char *' <NullToPointer>

    `-CharacterLiteral 0x5ec3bd8 <col:13> 'char' 0
