The reason is that for this particular test, the number of bits required for the test is random. Read the description of the test. The test runs until it has found n disjoint blocks of successive 1's. If the 1's happen to be more clustered than usual, more bits will be required. In fact, the total number of bits required for the test, named Y, is one of the test statistics: The RNG fails this test when Y is too large!

If I edit my code to just spit out a series of all 1's for the failing file the test will not fail. To me it seems like there is a series of values in the file which is causing ufile.c to fail when reading. This should not be the case if I'm trying to evaluate a set of random numbers.
The following the the error for the Sstring_run test.
N=1, n=1002700, r=0, s=32
5013504 bits have been read End-of-file detected. Not enough bits in file for these tests parameters
