yes - i see now it is a different problem - and 0.05 does give the same 'ZeroDivide' error to be clear, my original result with the 'ZeroDivide' error was using the official debian package - i do not see the 'ZeroDivide' problem when compiling myself from git - but it is not clear that the -pie flag is the cause - i will CC to the debian packaging team "Debian GNU Smalltalk maintainers" as the deb package indicates; although i see it is (since April 2018) listed as an inactive mailing list - if no response i will file a bug report against the package `gcc -v` and `g++ -v` both show --enable-default-pie; but i can not expose the 'ZeroDivide' problem compiling myself - compiling with all of the following flags produce the same (non-error) result for 1e-4 and 0.05: $ make CFLAGS='-no-pie' $ make CFLAGS='-pie' $ make $ /usr/local/bin/gst GNU Smalltalk ready st> 0.05 0.05
