Calling GAP commands via gap("command") reacts badly sometimes

Component: basic arithmetic

Do you mean gap.eval('Read("myfile.txt")') is flaky? If so, can you give an example?

This is a misunderstanding about using gap(s) versus gap.eval(s). This is not a bug.
gap(s) is supposed to always create a new gap object.
