Running into issues with max mask length

[undeath]

There seems to be a bug with how hashcat processes hcmask files.

On the CLI this works:

Code:

hashcat -m0 da8e187436ef310167021504d28c9b68 -a3 "?b$(for x in $(seq 255) ; do echo -n 00; done)" --hex-charset

but when I do this:

Code:

echo "?b$(for x in $(seq 255) ; do echo -n 00; done)" > test.hcmask
hashcat -m0 da8e187436ef310167021504d28c9b68 -a3 test.hcmask --hex-charset

hashcat's status claims the mask is only 255 characters in total and fails to crack the hash. (as a side note, in the first example hashcat's status claims the mask is 511 characters long, lol)
