Sorry for my silence this time, I'm currently in that
busy-after-back-from-holidays state.

I managed to import 5.0.8-test-2 into Debian's Zsh packaging git
repository and it build fine locally.

But I had test suite failures when being build inside a Jenkins job.
Doesn't seem to be caused by the zsh updated though as the most recent
5.0.8 build failed at the very same test:

../../Test/A05execution.ztst: starting.
[…]
Running test: Check whether '$pipestatus[]' behaves.
Unable to change MONITOR option
Test successful.
Running test: Check $pipestatus with a known difficult case
Test successful.
Running test: Bug regression: piping a shell construct to an external process may hang
This test takes 5 seconds to fail...

Was testing: Bug regression: piping a shell construct to an external process may hang

The following may (or may not) help identifying the cause:
  This test checks for a file descriptor leak that could cause the left
  side of a pipe to block on write after the right side has exited
../../Test/A06assign.ztst: starting.

Details:
5.0.8-test-2: http://jenkins.grml.org/view/Debian/job/zsh-binaries/201/architecture=amd64/console
5.0.8: http://jenkins.grml.org/view/Debian/job/zsh-binaries/200/architecture=amd64/console

Will try to import and test 5.0.8-test-3 as soon as possible.

		Kind regards, Axel
