jpgd.cpp, line 3101 should be:
if (((req_comps == 1) && (decoder.get_num_components() == 1)) || ((req_comps == 
3) && (decoder.get_num_components() == 3)))

The original code is correct because on RGB images the jpeg_decompressor class returns 4 bytes/pixel:

if (((req_comps == 1) && (decoder.get_num_components() == 1)) || ((req_comps == 4) && (decoder.get_num_components() == 3)))
