[GiNaC-devel] ginac-1.8.8/cln-1.3.7/gcc-15.1.0 test failures

[Andrey G. Grozin]

Hello *,

I've compiled cln-1.3.7 and ginac-1.8.8 by gcc-15.1.0 on Gentoo linux (I'm 
the maintainer of the ginal package in this distro). Everything's fine. 
But when I run ginac tests, I get

x86_64-pc-linux-gnu-g++ -DHAVE_CONFIG_H -I. -I../config  -I./../ginac 
-I../ginac -DIN_GINAC   -O2 -march=alderlake -mabm -mno-cldemote -mno-kl
