I'm building a C99 app on ubuntu 10.4 using openssl. Valgrind is
reporting hundreds of the errors below. I have read through the
manual/help and used the techniques described in the excellent article
http://wiki.wxwidgets.org/Valgrind_Suppression_File_Howto.
99% of these are caused by a value created in RAND_load_file (I am
seperately investigating building openssl with -DPURIFY). I could get
rid of all these if I could tell Valgrind to ignore any value created by
RAND_load_file. Is there such a capability?
