This is most likely due to some issue on new/delete operators works, which are undergoing changes in the language. That is, a code issue on hotspot.
I don't know why you are seeing this on windows-x86 though. https://msdn.microsoft.com/en-us/library/mt723604.aspx suggests that you can disable this check by -Zc:sizedDealloc-. Do this by "configure --with-extra-cxxflags=Zc:sizedDealloc-".
On a meta-level: Is a JDK for Windows 32-bit just built no longer or is it completely abandoned as a platform?
Oracle is not building 32-bit Windows regularly, and I don't think anyone else is doing that. (Perhaps AdoptOpenJDK?) In such a scenario, the code quickly bit rots. There has been no decision as of yet to remove the code from the code base, but unless someone steps up to maintain the code base, it's unlikely to survive in the long term.
