Created attachment 744 [details] Example code OS: Ubuntu 16.04 LTS COMPILER: default version of gcc shipping with the OS (5.4.0) Computing -A*b gives segmentation fault if: - A is a dynamically-allocated matrix with an ODD number of rows - b is a statically-allocated vector As the attachment shows, if A has an EVEN number of rows everything is alright If b is dynamically-allocated everything is alright.

I cannot reproduce. What are your compiler flags?
Comment 2 Gael Guennebaud 2016-10-12 14:54:14 UTC
ok, that fails with rc1, but this has already been fixed. *** This bug has been marked as a duplicate of bug 1311 ***
