Unit test ImportVAArgExpr fails on Windows. The source file:
void declToImport(__builtin_va_list list, ...) {
(void)__builtin_va_arg(list, int);
}
When compiled on Windows it produces AST:
TranslationUnitDecl 0x638f150 <<invalid sloc>> <invalid sloc>
<skipped>
`-FunctionDecl 0x638f780 <test.cpp:1:1, line:3:1> line:1:6 declToImport
'void (__builtin_va_list, ...)'
|-ParmVarDecl 0x638f6e0 <col:19, col:37> col:37 used list
'__builtin_va_list':'char *'
`-CompoundStmt 0x638f880 <col:48, line:3:1>
`-CStyleCastExpr 0x638f868 <line:2:3, col:35> 'void' <ToVoid>
`-VAArgExpr 0x638f848 <col:9, col:35> 'int'
`-DeclRefExpr 0x638f820 <col:26> '__builtin_va_list':'char *'
lvalue ParmVar 0x638f6e0 'list' '__builtin_va_list':'char *'
while on Linux 64 the result is:
TranslationUnitDecl 0x9fef870 <<invalid sloc>> <invalid sloc>
<skipped>
`-FunctionDecl 0xa046700 <test-imp.cpp:1:1, line:3:1> line:1:6 declToImport

Maybe it can help.
