The diagnostic for the following invalid code snippet is hosed on mainline
(this only affects the C++ frontend):
==========================
void foo()
{
if (({int c[2];})) ;
}
==========================
bug.cc: In function 'void foo()':
bug.cc:3: error: could not convert '{#'decl_expr' not supported by
dump_expr#<expression error>}' to 'bool'
Older versions handle this correctly:
bug.cc: In function `void foo()':
bug.cc:3: error: could not convert `({...})' to `bool'
