Bug in VirtualAllocEx after some recent Windows 10 update? RRS feed

    Hello,

    My dev team found a strange problem with VirtualAllocEx function after calling this function from 32bit binary but the HANDLE to hProcess was a 64bit process (actually this was a bug we didn't see in the past). VirtualAllocEx succeedes and returns a valid pointer but calling VirtualFreeEx does not free this memory. This doesn't happen on a PC without latest Windows 10 updates.

    Any ideas?

    Thanks.
