Hi everyone,
after updating sympy to 0.7.4, some of our code calling dsolve seems to go
into an infinite recursion and errors out with "maximum recursion depth
exceeded". A simple example demonstrating the issue is the following:
>>> f = Function('f')
>>> t = Symbol('t')
>>> dsolve(Eq(Derivative(f(t), t), 1.0), f(t))
In 0.7.3, this yields
f(t) == C1 + 1.0*t
but in 0.7.4 it goes into the infinite recursion. The issue seems to have
to do with the floating point constant, replacing it with an integer number
for example makes everything work.
Is there something wrong in my use of dsolve or is it a genuine bug in
0.7.4?
Thanks in advance, best
Marcel
