rtest15, Problem 174



Hi,
 I just installed Maxima from the Ubuntu repository and ran
all the tests. On the first run through, all tests passed with
no errors. I tried a second time with the processor running
at full speed, and on the second run found the following message:


Running tests in rtest15: 
********************** Problem 174 ***************
Input:
exp(1.0b-1)

Result:
1.10517091807564763b0

This differed from the expected result:
1.105170918075648b0

218/219 tests passed (not counting 1 expected errors).

It turns out not to be dependent on the processor speed, but
only on *when* the test is run: If Maxima is re-started then
all tests pass with no problems, but subsequent runs of the
test produce the error, even if I have Maxima clear the 
memory (e.g., Maxima > clear memory > kill all).

Any ideas?
