gdb tells me:

#0  NaNChecker::CHECK_DATA<double> ()
    at /home/knarf/TMP/configs/L2/build/NaNChecker/NaNCheck.cc:644
#1  0x00007ffff35b36b6 in ?? () from 
/usr/lib/x86_64-linux-gnu/libgomp.so.1
#2  0x00007ffff6eb9494 in start_thread (arg=0x7fffd4031700) at 
pthread_create.c:333
#3  0x00007ffff30cfaff in clone () at 
../sysdeps/unix/sysv/linux/x86_64/clone.S:97

So the segfault actually happens in NanChecker, trying to access 
_data[i=0:nelems] in CHECK_DATA.

Is SphericalHarmonicReconGen doing something strange with the Cactus 
infrastructure, or does this more point to some memory garbage?
