Historically, the tpm->data.emulator.activePcrBanks member was an unsigned int but since it was used as a bitmap it was converted to virBitmap type instead. Now, the virBitmap is allocated inside of virDomainTPMDefParseXML() but only if <activePcrBanks/> was found with at last one child element. Otherwise it stays NULL. Fast forward to starting a domain with TPM 2.0 and no <activePcrBanks/> configured. Eventually, qemuTPMEmulatorBuildCommand() is called, which subsequently calls qemuTPMEmulatorReconfigure() and finally qemuTPMPcrBankBitmapToStr() passing the NULL value. Before rewrite to virBitmap this function would return NULL for empty activePcrBanks but now, well, now it crashes.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
