Yes, there is a bug in snn.lib regarding pipes. And I fixed it, waiting for Walter to incorporate it :) I needed it for the new std.process.

What it comes down to is, DMC's FILE * implementation does not expect some of the quirks of pipe HANDLEs. For instance, if you open a FILE * around a pipe handle, it still tries to do a seek on that handle, and crashes. Also, when the write end of a pipe is closed, reading from the read end results in EPIPE from ReadFile, but this is translated to EBADF by the runtime. Therefore, FILE * sets an error instead of EOF.

Is the email address you have for this message correct? If so, I can send you a new version of snn.lib to try linking your code against (if you are willing to go through these steps), to see if it fixes your problem.

Using the command line dmd to build should be sufficient (I think).

Thanks for the email.

It seems like it still crashes from SciTE, though. :(
When I try debugging, I see it's doing so inside _close() which is /immediately/ above kernel32.dll!@BaseThreadInitThunk@12() -- in other words, it seems to be called directly from the entrypoint of the program, assuming it hasn't undergone optimizations. The error is: 0xC0000008: An invalid handle was specified.

Is there any other place in which this can happen?

Hm... its hard for me to say. Why would it be calling _close before main() is called? Very strange. Is there any more stack information?

Can you get it to crash by using a pipe from the command line?

In other words:

myprogram | more

or echo hi | miprogram

?

If this isn't killing the program in the same way, then it might be a different issue than the one I fixed.
