#4665 wrong TeX output with unary plus in exponent

[Keno Wehr]

The result of

simp:false;
tex1(x^+y);

is x+^{y}, but should be x^{+y}.

What version? I don't see this issue with current git HEAD:

(%i1) simp:false;
(%o1)                                false
(%i2) tex1(x^+y);
(%o2)                               x^{+y}

[Stavros Macrakis]

Same in the slightly older release Maxima 5.48.1 SBCL 2.5.7

[Keno Wehr]

Tested with 5.44.0 and 5.45.1.
The systems I use don’t have newer versions, sorry.

Could you build your own?

In any case, I'm closing this report since it doesn't happen with recent versions of Maxima.
