Unlikely to be relevant, but this is on Ubuntu vivid (15.04). No downstream bug
filed as yet.

[Bug binutils/18995] New: c++filt segfault on line not containing a symbol

[michael at slashhome dot org]

https://sourceware.org/bugzilla/show_bug.cgi?id=18995

Bug ID: 18995
   Summary: c++filt segfault on line not containing a symbol
   Product: binutils
   Version: 2.25
Status: NEW
  Severity: normal
  Priority: P2
 Component: binutils
  Assignee: unassigned at sourceware dot org
  Reporter: michael at slashhome dot org
  Target Milestone: ---

c++filt -t <<< "# Event count (approx.): 746034049125"
segfault

Does not happen without -t.

Not-very-useful backtrace since I just have a stripped binary:
