That is very strange.  And I cannot reproduce it.  Under Linux I get:

heiner@drb7 <52> ./achest -LSr problem
CHEST version 3.19, 18-Dec-1999
Options = -LSr
Input file: 'problem'
Reading job:
W:  Kb4 Dd1 Te8 Lb2 Bd5 (5)
S:  Kb7 La6 Bb6 Bb5 (4)
FEN: 4R3/1k6/bp6/1p1P4/1K6/8/1B6/3Q4 w - -
analysing (mate in 3 moves):
Solution (in 3 moves):
        Lb2 - h8
Time (virt) = 0.030 sec

 Lh8 Ka7 Da1  Kb7 Dg7+
     Kc7 Dc2+ Kb7 Dh7+
              -*- Dc6+

end of solution tree
Total Time (virt) = 0.030 sec
heiner@drb7 <53> setenv CHEST_OPTS -ll
heiner@drb7 <54> ./achest -LSr problem
CHEST version 3.19, 18-Dec-1999
Options = -ll
Options = -LSr
Input file: 'problem'
Reading job:
W:  Kb4 Dd1 Te8 Lb2 Bd5 (5)
S:  Kb7 La6 Bb6 Bb5 (4)
FEN: 4R3/1k6/bp6/1p1P4/1K6/8/1B6/3Q4 w - -
analysing (mate in 3 moves):
Solution (in 3 moves):
        Lb2 - h8
Time (virt) = 0.020 sec

 Lh8 Ka7 Da1  Kb7 Dg7+
     Kc7 Dc2+ Kb7 Dh7+
              -*- Dc6+

end of solution tree
Total Time (virt) = 0.020 sec


The above is the intended behaviour.
I have no idea, what kind of problem or bug causes the behaviour you observe.
Any chance your binary is corrupted somehow?

Sorry for not being more helpful.
