[ADOL-C] taylorexam.cpp fails

[Asbjoern Burow]

Dear developers,

I currently learn how to use ADOL-C and run some of the tests from the  
distribution. I have a runtime problem with the 'tensor_eval' function  
when running the taylorexam.cpp. I am unsure in the moment if it is  
due to a wrong ADOL-C usage/setup/compilation or if it is a  
known/reproducible bug. Some other tests run fine, e.g.,  
speelpenning.cpp.

I tested this with
  - ADOL-C version 2.6.2/2.6.3 on a Mac (x86_apple_darwin) with g++ compiler
  - ADOL-C version 2.6.2 on CentOS Linux 7.5 with icpc 2018 compiler

For output from the tests see below. If further information is  
required, e.g., the config.log from ADOL-C compilation, please just  
tell me.

I appreciate any hints or assistance to figure this out.
Best,
Asbjoern
