stdin piping has problem on windows

[jeiea]

From image-pnm.cpp,

bool image_load_pnm(const char *filename, Image& image) {
    FILE *fp = NULL;
    if (!strcmp(filename,"-")) fp = stdin;
    else fp = fopen(filename,"rb");

Default of stdin is text mode on windows, and it regards 1A byte as EOF.
According to related stackoverflow post, setmode can be the solution.
When I discovered this problem, this appeared with crash due to use of array index -1.

Thanks for the report! Should be fixed now.

It's not fixed. I've just checked on Win10 RS1.
