I am trying to get GCC-XML to be able to process a large C++ code base on
Windows. Things work very well on Linux and Mac OS X, but on Windows, I get
an internal compiler error. I have built GCC-XML from the CVS HEAD sources
as of yesterday, and I am using it to emulate Visual C++ 9.0 SP1. The error
output is attached, and the preprocessed source can be found here:
http://www.infiscape.com/misc/output.cpp.bz2
Are there any tips for debugging something like this?
Thanks for the preprocessed file. I did a binary search through it,
incrementally truncating the second half of the remaining region.
Here is a minimal case to reproduce the ICE:
class A {};
struct __attribute__((dllimport)) B: virtual public A { ~B() {} };
It only happens on windows. It has something to do with the dllimport
attribute, virtual inheritance, and the destructor. I'll investigate
further when I get a chance.
In your file, 'B' is really LogOStream, and 'A' is std::ostream (which
is what actually does the virtual inheritance from something else).
In addition to the ICE, I am getting some unexpected errors about there not
being an overload of operator<< for the std::setbase() case. I do not know
if that is strictly a problem, but if there is a way to fix that, too, that
would be great.
I'll look at this if it still happens after fixing the first issue.
