#13 error in convertSFS_Code for ms conversion

[Anonymous]

After simulation based on:
./sfs_code 1 1 --theta 0.0004 --rho 0.0004 --popSize 10000 -Tg 0 184.2 -TE 0.025 --sampSize 4000 -L 3 8500 8500 8500 --linkage g 0.0001 --selDistType L 2 1 5000 1.0 0 --outfile 'sfsout.txt' --errfile 'sfserror.txt'
(which works fine)

I tried to convert to the ms format. This worked for me in the past with other simulations, but not this one:
/net/fantasia/home/rsrothwe/SFS_CODE/bin/./convertSFS_CODE sfsout.txt --ms F msout.txt

I received the following error and no output:
*** glibc detected *** /net/fantasia/home/rsrothwe/SFS_CODE/bin/./convertSFS_CODE: realloc(): invalid next size: 0x00000000006d0f80 ***
