I think malloc is used when a failure is not to be considered
fatal, e.g., when the size of the data is determined by the input.
Doug went through and fixed a bunch a while ago (yearly 2009).
You should be able to find the discussions around the patches
in the archives. Basically, if there's no explicit check
for NULL after malloc, then it's quite likely a new call
that went in after Doug's fixes.
