[Bug 1753296] [NEW] xfburn crashed with SIGSEGV in malloc_consolidate()

[Stephen Michael Kellat]

Public bug reported:

I left the laptop idle on a stable surface to burn an ISO file after
previously failing to burn a disc.  After touching the touchpad to
resume the session after burning completed, this error was presented.
