Hi, I am trying to perform ElimLin on the PRESENT polynomial system of equations generated by present.py written by Martin Albrecht (available here: https://bitbucket.org/malb/research-snippets/src/0b91079cf8b2e71141dc800b811173c8b1f5dd02/present.py?at=default)
I followed exactly the same commands as written on slide 24 of http://sage.math.washington.edu/home/malb/talks/20100622%20-%20Algebraic%20Tools%20-%20Tools%20-%20Egham.pdf. However, when it comes to the ElimLin step, I encounter the error: ------------------------------------------------------------------------------- Unhandled SIGSEGV: A segmentation fault occurred in Sage. This probably occurred because a *compiled* component of Sage has a bug in it and is not properly wrapped with sign_on(), sig_off(). You might want to run Sage under gdb with 'sage -gdb' to debug this. Sage will now terminate. ------------------------------------------------------------------------------- I'm running Sage Version 5.7 on 64-bit Linux version 2.6 (Red Hat 4.4.7-3). Could anyone enlighten me on what the problem is here? Greatly appreciate any help. Thanks! -- You received this message because you are subscribed to the Google Groups "sage-support" group.
