When I ran openssl-0.9.5a's "make test", the tmp.bntest file that was
written contained (out of 1800+ tests) seven expressions which Solaris 7's
'bc' evaluated to give non-zero results.
Repeated runs of 'bc' on the same tmp.bntest file gives identical results.
I get the same anomalous results (i.e. diff says the output files are
identical) whether I am on Solaris-SPARC or on Solaris-Intel.
Nine other tmp.bntest files that I produced by rerunning "make test" did
not contain any expressions that bc had a problem with.
When I feed the problematic tmp.bntest to GNU bc (version 1.05a, on Red Hat
Linux 6.2) all the expressions evaluate to zero, as they should.
My concern is this: Do the BN library and GNU 'bc' agree with each other
because they are both right (and the Solaris 'bc' has a bug), or do the BN
library and GNU 'bc' agree with each other because they each have the same
bug (and the Solaris 'bc' is giving correct answers)?
