Bug #: 53336
Summary: invalid types in nop conversion
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: dcb314@hotmail.com
Created attachment 27392
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27392
gzipped C++ source code
I just tried to compile the package boost-1.48.0-13
on gcc-4.8 trunk dated 20120513 on an AMD x86_64 box.
The compiler said
/home/dcb/rpmbuild/BUILD/boost_1_48_0/libs/iostreams/src/mapped_file.cpp: In
member function 'boost::iostreams::mapped_file_source::operator
boost::iostreams::mapped_file_source::safe_bool() const':
/home/dcb/rpmbuild/BUILD/boost_1_48_0/libs/iostreams/src/mapped_file.cpp:454:1:
error: invalid types in nop conversion

^
<<< Unknown tree: offset_type >>>

--- Comment #1 from Nathan Ridge <zeratul976 at hotmail dot com> 2012-05-14 08:50:53 UTC ---
Reduced testcase:
bool foo();
struct C
{
C()
{
if (foo())
foo();
}
};
struct S
{
struct dummy
{
int i_;
};
typedef int dummy::*bool_type;
operator bool_type() const
{
return foo() ? &dummy::i_ : 0;
}
};
int x;
struct adaptor
{
C c;
virtual void bar()
{
if (S())
x = 0;
}
};
int main()
{
adaptor a;
}
Compile with -O2. Errors:
test.cpp: In member function 'virtual void adaptor::bar()':
test.cpp:32:18: error: invalid types in nop conversion
virtual void bar()
^
<<< Unknown tree: offset_type >>>
bool
D.2314_1 = (<<< Unknown tree: offset_type >>>) D.2313_9;
test.cpp:32:18: internal compiler error: verify_gimple failed
