Try a variant without space after obj:

As far as I can see, the manual for suppression does not describe any
character being special apart of * and ?.
And the suppression parsing code just skips 4 characters when it
recognises obj:

So, space is not special, and the matching logic will try to find 
  <space>*/libcrypto.so.1.0.0
or similar.
