From [http://ask.sagemath.org/question/3464/integral-failing-with-
segmentation-fault this ask question]:
{{{
sage: ys=0.06+2*(x-0.0275)
sage: xs=ys/1.516
sage: i=1/(xs/(1+xs)-x/(1+x))
sage: integral(i,x)
250/121*x^2 + 423541/58564*x + 86958139/28344976*log(484*x + 5)
}}}
But, the same integral with boundaries:
{{{
sage: integral(i,x,0,0.275)
}}}
leads to a series of lines of the form:
{{{
;;;
;;; Detected access to protected memory, also kwown as 'bus or
segmentation fault'.
;;; Jumping to the outermost toplevel prompt
;;;
}}}
