MosaikAligner has segmentation fault for solid pair-end reads

What steps will reproduce the problem?
1. Data: Solid pair-end data
e.g.,
>2_45_92_F3
T20..20..0302.220002..31..3.0..2.2..3.1...23...03..
>2_45_148_F3
T30..12..3030.200112..21..2.3..1.3..2.1...13...23..

and 
>2_45_92_R3
T12.03...320.3.01.11002.3113.31103.0
>2_45_148_R3
T02.03...110.0.30.01001.1003.01013.0

2. I build the reads, the reference and the jump database and then do alignment 
using MosaikAligner. 

What is the expected output? What do you see instead?
I saw the following:

What version of the product are you using? On what operating system?
Mosaik 1.1.0021 on Linux (tried both cluster and a 16 core computer) 

Please provide any additional information below.

For different parameter setting, the errors occur at different time, e.g.,

for the following command:

/share/data/program/mosaik-aligner/bin/MosaikAligner -in 
Pla0000325047_1_PE_HS26611_1.dat -out 
Pla0000325047_1_PE_HS26611_1_aligned_34.dat -ia human_all_color.dat  -ibs 
human_all_base.dat -j human_all_base_15  -p 8 -hs 15 -mm 10 -act 20 -mhp 100
the error occurs when 9% of the reads are aligned.

If I change -act 25, the error occurs when 52% of the reads are aligned.

However, if I change -mm 4, the error occurs at the beginning and 0% of the 
reads are aligned.

If I use the following command, no errors will occur. But the results are 
really bad.

/share/data/program/mosaik-aligner/bin/MosaikAligner -in 
Pla0000325047_1_PE_HS26611_1.dat -out Pla0000325047_1_PE_HS26611_1_aligned.dat
