When GetProcessInformation() obtains SystemProcessInformation, it resizes its buffer as directed by NtQuerySystemInformation(). Nothing of value resides in the old buffer if a resize is attempted, so it can be freed before attempting to allocate a resized one. This may help crashes like go/crash/f385e94c80000000, which experience out-of-memory while attempting to allocate a resized buffer. It also may not help, because the required buffer size may just be too large to fit in memory. See https://crashpad.chromium.org/bug/143#c19.
