Description:

I am getting a segmentation fault with gcc 11.1.0.
With gcc 10.2.0-3 (from community repository) I can compile the same code without any issues.


$ gcc polytools.c -o polytools.o
during RTL pass: expand
polytools.c: In function ‘poly_gauss_jacobi_h’:
polytools.c:128:3: internal compiler error: Segmentation fault

*edit: I changed the c file during the writing of this bug report to add a main function. The command I ran to get the error message is "$ gcc polytools.c" and not "$ gcc polytools.c -o polytools.o".

% gcc polytools.c
