We've seen this before, on an Alpha. Something is wrong in the configure,
for the code reads
if (read(*handle, &d1, size) <= 0) goto enddata;
if (*swapbytes) swap(&d1, size);
result[i] = d1;
#if SIZEOF_LONG_DOUBLE > 8
case sizeof(long double):
if (read(*handle, &e1, size) <= 0) goto enddata;
if (*swapbytes) swap(&e1, size);
result[i] = (double) e1;
so this will only happen if sizeof(long double) is 8 and
SIZEOF_LONG_DOUBLE > 8. I am very surprised that sizeof(long double)
is 8 on a 64-bit machine (SGI or Alpha) but that may reflect limitations
What does src/config.h say SIZEOF_LONG_DOUBLE is?
I can only presume that you have different compilers or compiler options
at configure and build times. You may need to set CC=gcc, for example.
As a more general point, there is nothing in Rstreams that cannot be done
with binary connections, except reading S data objects which package
foreign now covers. So for new code, use the alternatives.
