You are damned right, quite a bad mistake. 

Thank you,

Benedikt,

numeric_limits::min() is 2.22507e-308 - you
want

-numeric_limits::max() or -COIN_DBL_MAX

Hi all,
at the moment I am trying to solve
a mixed-integer problem. Actually the
integers are not really integers, I
nailed them down to booleans through
upper and lower bounds. The problem
is, that the clp can not solve the
problem, it says "Clp6002E 1 bad bound
pairs or bad objectives were found
-
first at R0", but the glpk is able to
get the right solution. I've reduced
the problem as much as possible and
attached it to this mail.
Could that be a bug or am I using the interface
wrong?

Thanks,
Benedikt
