Hi Hez,

Just to clarify, the above comment was directed at Hazen, but if you want to
also have a go at comparing cairo.c and psttf.cc to find the bug, that would
be fine.  As the other core developers know, I am in the peculiar position
of having a good overview of PLplot through its build system and python
interface, but I am not really that comfortable with C or C++.  Thus, for
core C library or device driver bugs such as you have found my role is
mostly restricted to testing and confirming such issues while cheering on
others to actually fix them.

Alan
