I can indeed replicate with the LIBKML driver on Windows (probably by libkml itself), and this 
is specific to this combination. From testing, it appears that the presence of newline
+tabulations without spaces between coordinate triplets is the cause of the issue, where 
libkml doesn't detect properly the start of the x coordinate of the new triplet and mangles it 
with the z of the previous one.

As a workaround, you might define OGR_SKIP=LIBKML as configuration option to exclude the 
LIBKML driver and use the "old" KML one that has not that issue.

Or edit the file to replace tabulations by spaces.
