According to a comment in grokdeclarator in file gcc/cp/decl.c:
/* If we just have "complex", it is equivalent to
"complex double", but if any modifiers at all are specified it is
the complex form of TYPE. E.g, "complex short" is
"complex short int". */
Yet, __complex is equivalent to __complex int as shows the following testcase:
#include <typeinfo>
int
main (void)
{
return typeid (__complex) != typeid (__complex int);
}
The following patch fix the problem.
ChangeLog are as follows:
*** gcc/cp/ChangeLog ***
2014-09-26 Thomas Preud'homme <thomas.preudho...@arm.com>
* decl.c (grokdeclarator): Set defaulted_int when defaulting to int
because type is null.
*** gcc/testsuite/ChangeLog ***
2014-10-26 Thomas Preud'homme <thomas.preudho...@arm.com>
* g++.dg/torture/pr63366.C: New test.

Is this ok for trunk?
