Trying to solve 4 very large polynomials, and after defining one of the polynomials I get the error: Code: free(): invalid pointer

Please provide an example which can reproduce it - so that we can fix the bug. |

Hi Hannes, I'm unable to comment the code I am using as it above the character limit of a message. Have registered to allow posting a URL to a text file containing the code however am waiting on account activation. Best, Angus |

Hi Hannes, A link to the script I am running can be found below. drive.google.com/file/d/1F-k7Q_LjCIZag2kO8SNDO8qM9AFdALKj/view?usp=sharing It contains 4 polynomials in 4 variables, that are quite long and large, and is attempting to solve them to find all solutions. I have one known solution already, so know they can be solved. Angus |

Probably "out of memeory": it needs >300GB of RAM. |
