Something between 1.616_901 and 1.616_902 changed which breaks fork() in DBI on Windows. The test 16destroy.t fails with a Windows error
"This application has requested the Runtime to terminate in an unusual way"
Initially I saw this in 1.617 but then I stepped backwards to find the problem occurred between these 2 versions. Some smokers have reported this problem in 5.10.1, 5.14.0 and 5.14.2. I can reproduce on my wife's netbook which is strawberry perl 5.12.0.
As you'll see from the Changes file the only 2 entries added were:
Enhanced performance for threaded perls (Dave Mitchell, Tim Bunce)
Added note to DBI::Profile about async queries (Marcel Gr<FC>nauer).
I've diffed the two versions but there were quite a lot of changes and so far I cannot locate the problem. I've given up for tonight but might find time to do more.
I have a vastly reduced 16destroy.t which still demonstrates the problem if it helps anyone.
