This src/raster/ftrend1.c problem seems not Mac-related. It also caused the
problem I was suffering, and reported some weeks ago, on my OpenVMS system.
So it is NOT the byte order,
since OpenVMS is little endian just like Intel/Linux.
The latest CVS version changed one line in ftrend1.c (see diff's below). The
old one (FTREND1.C;9) just works fine, the current one causes that, on
OpenVMS, data is written outside data-pace into the executable code of the
program, which causes a spectacular crash!!!!

When I did some debugging, as far as I got because of memory problems,
I saw that the width and heights of the characters in bitmaps gave some
unexpected values.

Why was this line in FTREND1.C changed anyway, and please check if this code
is correct.
