#3346 texput broken

[philippe Roux]

texput doesn't work in maxima 5.41 (%i6 output should be like %o5 and %i7 should ouput $$ %i5 $$)

(%i2) define(ln(x),log(x))
(%o2)                           ln(x) := log(x)
(%i3) texlog(x):=block([],concat("\\ln\\left(",tex1(x),"\\right)"))
(%i4) texput(ln,texlog)
(%o4)                               texlog
(%i5) texlog(x)
(%o5)                          \ln\left(x\right)
(%i6) tex1(ln(x))
(%o6)                               \log x
(%i7) tex(ln(x))
$$\log x$$

and sometimes generate a stackoverflow, example :

texlog1(x):=block([],concat("\\ln(",tex1(x),")"))$
texput(log,texlog1);
texlog1(x);
tex(log(x));

maxima crash just after tex(log(x)) with message "Exiting on signal 6". In wxmaxima 15.8.2 I also get informations :

Message from maxima's stderr stream:

It appears to me that both of these problems are not bugs in Maxima.

(1) Given ln(x) := log(x), then tex(ln(x)) is going to output log(x) (since ln(x) evaluates to log(x). Note that tex sees log(x), not ln(x), so the texput for ln doesn't come into play.

(2) You have defined the TeX output for log in terms of the TeX output for log -- of course that leads to a stack overflow.

Closing this as "won't fix" as it doesn't appear to be a bug in Maxima.
