Here you go:
$ curl -O https://raw.githubusercontent.com/malaterre/gcc-110622/main/new/testcase.i
$ curl -O https://raw.githubusercontent.com/malaterre/gcc-110622/main/new/check.sh
$ chmod +x check.sh
$ schroot -c sid32
$ cvise check.sh testcase.i
If you do not have a sid32 chroot, you may want to use
barriere.debian.org + sid_i386-dchroot

that works for me in a sid32 chroot, and also in a sid chroot.

In my case:
% ls -ld /dev/shm
drwxr-xr-x 2 root root 40 Aug 24 11:31 /dev/shm
on barriere.d.o:
% ls -ld /dev/shm
drwxrwxrwt 2 root root 40 Aug 25 06:28 /dev/shm
How did you setup your schroot ? Mine is:
% cat /etc/schroot/schroot.conf
