IPC-Run 0.79 t/run.t hangs on Cygwin

I wish I had more information for you, but, unfortunately, I don't. On Cygwin, the test t/run.t hangs after the 63rd test. Below is the output from the test after running "perl -Ilib t/run.t". I let it hang for at least five minutes before exiting. ok 40 ok 41 ok 42 ok 43 ok 44 ok 45 ok 46 ok 47 ok 48 ok 49 ok 50 ok 51 ok 52 ok 53 ok 54 ok 55 ok 56 ok 57 ok 58 ok 59 ok 60 ok 61 ok 62 ok 63

No worries - can you run it with env IPCRUNDEBUG=4 set, as the Makefile.PL's help text indicates? - R. On Jan 21, 2005, at 6:44 AM, via RT wrote: Show quoted text

Attached is the verbose output from the test until it hangs. Hope it helps. Steve Peters steve@fisharerojo.org [rs@ordata.com - Fri Jan 21 17:05:45 2005]: Show quoted text

Same with IPC::Run 0.80. $ perl -v This is perl, v5.8.7 built for cygwin-thread-multi-64int But run.t passes without зкщидуьы on Win32 without Cygwin.
