LDMS --ld-score-region no output

Dear Jian,

Currently we are trying to use your GREML-LDMS to perform a heritability analysis on our HRC1.1 imputed data. Unfortunately we hit a bit of a problem right from the start, namely the --ld-score-region command not producing any output, without parsing any errors. Do you have any idea what might cause this behavior? Below are the command used and a tail of the strace.
Command:
gcta64_1902 --dosage-mach-gz Dosages/chr22.mach.dose.gz Dosages/chr22.mach.info --ld-score-region 200 --out chr22Strace tail:

Alternatively I tried to perform roughly the same analysis using the normal LD command as follows:

gcta64_1902 --dosage-mach-gz Dosages/chr22.mach.dose.gz Dosages/chr22.mach.info --ld-score --ld-wind 200 --ld-rsq-cutoff 0.01 --out chr22
However, this produces a segmentation fault right after finishing loading in the dosage data (without threading).

Might this be caused by us using mach dosage files instead of plink format dosage/genotype files?

Thanks in forward for looking into this!
