## Submitted by Jitse Niesen Assigned to **Nobody** **[Link to original bugzilla bug (#195)](https://eigen.tuxfamily.org/bz/show_bug.cgi?id=195)** **Version**: 3.0 **Operating system**: Linux ## Description Created attachment 108 test program I ran the test suite in Debug mode and to my surprise some of the tests fail (see http://eigen.tuxfamily.org/CDash/viewTest.php?onlyfailed&buildid=5090 ; that run was not done with the latest version of Eigen). In particular, the conservative_resize_1 test failed. I boiled it down to the attached test case. It extends the matrix m using conservativeResizeLike(). For some reason, one of the coefficients of m is not copied over into the new matrix. All other coefficients are correct. The output of the attached program is Before: m(37,40) = -649311 Before: n(37,40) = -649311 Resizing m to be 66 by 58 After: m(37,40) = -125023 After: n(37,40) = -649311 I compiled the program using GCC 4.3.3 with -msse2 and no other compile flags, 32-bits Linux Fedora, current version of Eigen3. **Attachment 108**, "test program": [rt.cpp](/uploads/c4dad1be7158b88e257d8909aabca130/rt.cpp) ### Blocking #25
