Summary: PCH crash with conflicting identifiers
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs

While attempting to hack around precompiled headers, I discovered that the
following managed to elicit a pure virtual function call crash. Filing
immediately; haven't performed any reduction yet.
// Test this without pch.
// RUN: %clang_cc1 -DPASS1 -DPASS2 -std=c++0x -fsyntax-only -verify %s
// Test with pch.
// RUN: %clang_cc1 -x c++-header -DPASS1 -std=c++0x -emit-pch -o %t %s
// RUN: %clang_cc1 -DPASS2 -std=c++0x -include-pch %t -fsyntax-only -verify %s
#ifdef PASS1
struct foo {
foo(int) : foo() { } // expected-note{{it delegates to}}
foo();
};
#undef PASS1
#endif
#ifdef PASS2
foo::foo() : foo(1) { } // expected-error{{creates a delegation cycle}} \
// expected-note{{which delegates to}}
#endif
