Can you try checking the value of fontLen before / after call to
readEmbFontFile?  That variable is not initialized anywhere, if you happen to
have it set to 0 (or <= 3), it will avoid crash for TrueType font:

http://cgit.freedesktop.org/poppler/poppler/tree/fofi/FoFiBase.cc#n150

called from FoFiTrueType::parse().  So you may not see the crash on certain
builds.  Forcing fontLen to non-0 value prior to call to readEmbFontFile can
help reproduce.
