Trying to solve 4 very large polynomials, and after defining one of the polynomials I get the error:

Code:
free(): invalid pointer
Singular : signal 6 (v: 4132):
current line:>>)^103*x(2)^2*x(3)^3+7.4585*bigint(10)^101*x(1)*x(2)^2*x(3)^3+1.80552*bigint(10)<<

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.
