--- Comment #1 from novae.harpist06@icloud.com --- Created attachment 79007 --> http://bugs.winehq.org/attachment.cgi?id=79007 original dbgcore example
This issue was original discovered by trying to use official microsoft dbgcore/dbghelp to produce crash dumps. Looking at the syscalls you can see it obviously deadlock while trying to iterate over memory using MemoryRegionInformation.
