Hi,

Please have a look at the attached c code -- I'm writing a function to solve polynomial problems. The issue is that variable b's value changes when the function polynomial was called for the first time.

I'm using version 0.9.25 windows binary from the website.

"tcc -run WTP_computation_test.c" here produces the text
