The following test scene parses fine in 3.7.0.4.
It fails to parse in 3.8/master at commit bb85b4fd on Sat Nov 18
22:10:56 2017 +0100.
In digging the last commit I've found which works is 2c4e9f2 on Fri Jun
13 09:50:05 2014 +0200. Some time between that commit and 9b10411 on Mon
Jul 21 23:17:10 2014 +0200 something changes such that we get this core
dump:
povray_9b10411: backend/parser/express.cpp:3129: boost::shared_ptr<X>
pov::Parser::Parse_Blend_List(int, pov::ColourBlendMapConstPtr, int)
[with MAP_T = pov::GenericPigmentBlendMap; pov::ColourBlendMapConstPtr =
boost::shared_ptr<const pov::ColourBlendMap>]: Assertion `Blend_Type ==
PIGMENT_TYPE' failed. Aborted (core dumped)
At some point between d1d01eb on Fri Sep 18 19:12:10 2015 and eeeb2c5 on
Sun Jan 3 02:13:09 2016 the core dump is fixed and we start to get part
of the parse error which carries forward to the present day.
Still digging, but no more time for it today and unsure when I can get
back to it. Posting what I have.

I updated to the current release/3.8.0 and this is fixed - thanks.
Given there was a performance related parser update too - and that I'd
not run parser tests since last summer, I ran all the sample scenes,
shipped includes and the small-ish set of parser test cases I have in my
space against release/3.8.0. All OK for what was tested.
