I get the EOF error too, triggered by normal maths functions with real arguments, e.g. exp(2), sin(2).
I do NOT get the error from 'x+x' if x is already defined (e.g. if x=5, then x+x gives 10). I do get the error if I type x+x while x is still undefined. Does that suggest that my error from the functions indicates that those functions are not yet defined? Typing 'x(2)' (x undefined) also triggers the error. Referring to the EOF error mentioned in Bug#513853 ("fixed by dependency on libiml0 >= 1.0.3"), I do have that version of libiml installed. $ dpkg -l sagemath libiml0 ii libiml0 1.0.3-3 Integer Matrix Library, runtime files ii sagemath 3.0.5dfsg-2 Mathematics software written in Python -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
