ethminer 0.12 freezes after Win10 Fall Creators Update

[OlafSt]

After successfully installing Fall Creators Update my ethminer just freezes. Looks like this:

Z:\Geth\ethminer>ethminer.exe -G -v 8 --cl-global-work 16384 --cl-local-work 256 --opencl-platform 1 --farm-recheck 400 -F http://eth-eu.dwarfpool.com:80/adr/GPUMiner
  i  18:38:45|main      Found suitable OpenCL device [ Ellesmere ] with 8589934592  bytes of GPU memory
 cl  18:38:45|cl-0      No work. Pause for 3 s.
  m  18:38:45|main      Waiting for work package...
  m  18:38:45|main      Got work package: #143d72ce
  m  18:38:46|main      Speed   0.00 Mh/s    gpu/0  0.00  [A0+0:R0+0:F0] Time: 00:00
  m  18:38:46|main      Speed   0.00 Mh/s    gpu/0  0.00  [A0+0:R0+0:F0] Time: 00:00

  m  18:38:48|main      Speed   0.00 Mh/s    gpu/0  0.00  [A0+0:R0+0:F0] Time: 00:00
  m  18:38:48|main      Speed   0.00 Mh/s    gpu/0  0.00  [A0+0:R0+0:F0] Time: 00:00
 cl  18:38:48|cl-0      New work: header #143d72ce

Then ethminer freezes and nothing else happens. When switching to use the built-in GPU inside the CPU, the results are the same, using another pool for mining also didn't help. Process can be cancelled with CTRL-C so it looks like ethminer is waiting for something that doesn't happen.

Had the wild idea that Update KB4048955 (which locks up 24-Pin-Printers from Epson) may be the cause, but deinstalling it didn't help. KB4048954, which also locks up Epson needle Printers, is not installed here.

Any help greatly appreciated.

Same for me, ethminer just hang at New work: header ...

OK, it looks like the miner just can't log something to the terminal, but it still runs, it's not stuck there and doing nothing.

I have found a solution to this phenomenon. While working, ethminer switches to a new block. This looks like this:
`
cl 23:54:20|cl-0 Switch time 69 ms / 7303 us

cl 23:54:21|cl-1 New work: header #827b0938 target {some cryptic number}`

as you can see we have some garbage there at the end of the header number. This annoyed me and I switched the codepage of the CMD-Window to 65001 using the chcp command. This successfully Shows the real characters intended by Dwarfpool - but under some circumstances the output to CMD gets stuck.

Eliminating the chcp-call also eliminated the freezers.

@OlafSt Wow, adding chcp 437
at the head of the bat script actually works!!!
No more freeze now!

I think this issue can be closed.
