Hi Bill,

thanks, hopefully fixed in SVN 867.

Please keep in mind that '
make parallel ' is experimental and contains
bugs in ScalarFunction.cc that I was not able to reproduce because they
only occur sporadically.

If I do:

make clean

./configure  CORE_COUNT_WANTED=syl

make

everything is fine.

If I do:

Hi,

the problem is in *ScalarFunction.cc*. The compiler complains about a pointer
which is not
initialized in the constructor (which is on purpose, but the compiler seems not
to like it).

The pointer is initialized at a later point in time (at *ScalarFunction.cc:255*)
but the compiler
seems not to accept that.

Please try *SVN 865**.*
