I think your problem lies in the error function which can't be computed
in an explicit form, this is why nobody can convince mathematica to do the
computation.

However if a-d are number you can do it numerically:

In[3]:= NIntegrate[Evaluate[ Exp[-x^2]Erf[2 x + 1] Erf[ 4 x - 1] ], {x,-Infinity,Infinity}]

Out[3]= 0.442036
