Preprocessed source that GCC suggested attaching to the bug report

Description of problem:
When compiling examples from the eigen3 library, one of the tests triggers an Internal Compiler Error:

/home/rich/Source/eigen-eigen-65ee2328342f/unsupported/Eigen/src/MatrixFunctions/MatrixFunction.h: In member function ‘Eigen::MatrixFunction<MatrixType, 1>::DynMatrixType Eigen::MatrixFunction<MatrixType, 1>::solveTriangularSylvester(const DynMatrixType&, const DynMatrixType&, const DynMatrixType&) [with MatrixType = Eigen::Matrix<std::complex<double>, -0x00000000000000001, -0x00000000000000001>, Eigen::MatrixFunction<MatrixType, 1>::DynMatrixType = Eigen::Matrix<std::complex<double>, -0x00000000000000001, -0x00000000000000001>, typename MatrixType::Scalar = std::complex<double>]’:
/home/rich/Source/eigen-eigen-65ee2328342f/unsupported/Eigen/src/MatrixFunctions/MatrixFunction.h:468:2: internal compiler error: in convert_move, at expr.c:324

Version-Release number of selected component (if applicable):
gcc-4.6.0-0.15.fc15.x86_64

How reproducible:
Attempt to run "make doc" in the eigen3

Steps to Reproduce:
1. Download eigen3 source: http://bitbucket.org/eigen/eigen/get/3.0.0.tar.bz2
2. Extract source and build doc target using default settings (mkdir build; cd build; cmake ..; make doc)
3. Experience error
  
Actual results:
Compiler error

Expected results:
Examples build successfully.

Additional info:
The same source builds using gcc from Fedora 14 (tested in mock).

preprocessed source without extra rpmbuild flags

Accidentally uploaded a dump from rpmbuild, this dump doesn't have any of the extra cflags rpmbuild adds.
Comment 2 Tim Niemueller 2011-04-17 23:41:25 UTC 
This problem seems to be solved in the current F-15 version of GCC. I could compile eigen3 just fine with a little patch (see review). Rich, can you check and close this bug if it works for you?
Comment 3 Rich Mattes 2011-04-24 04:09:04 UTC 
I've checked, I'm no longer seeing this bug in the 4.6.0-5.fc15 release.  I'll go ahead and close this bug report.
