as far as i know, -dTextAlphaBits=4 -dGraphicsAlphaBits=4 make gs crash. 
because if textalphabits is used, apple-patented font hinting is 
needed.(although freetype library implemented alternative hinting, it 
doesn't migrated to gs.) so gs calls THROW_PATENTED which uses 
longjmp(yet i can't make sure why it crashed instead of showing error 
message), there is bug report regarding to this issue(but not for this 
sigsegv).

i think it would be okay if you remove textalphabits when invoking gs
