With Python3, the dict.value() method returns an iterator. If a dictionary is updated while an iterator on its keys is used, a RuntimeError is generated. Converting the iterator to a list() forces a copy of the mutable keys in an immutable list which can be safely iterated. Commitf8d11e5a4aconverted various uses but missed one: When specifying multiple BUILDTARGET, the first target builds successfully, but then the PGen.BuildDatabase._CACHE_ dictionary is updated, and accessing the next target triggers a RuntimeError. Convert this iterator to an immutable list, to solve this build error: $ build -a IA32 -t GCC5 -b RELEASE -b NOOPT -p OvmfPkg/OvmfPkgIa32.dsc [...] Processing meta-data ... build.py... : error C0DE: Unknown fatal error when processing [OvmfPkg/OvmfPkgIa32.dsc] (Please send email to edk2-devel@lists.01.org for help, attaching following call stack trace!)
