#7766: Segfault when skipping ahead with EIA-708 closed captions enabled
----------------------------------------------+-----------------------------
Reporter: Clayton Smith <argilo@…> | Owner: danielk
Type: patch | Status: new
Priority: minor | Milestone: unknown
Component: MythTV - ATSC | Version: head
Severity: medium | Mlocked: 0
----------------------------------------------+-----------------------------
A segfault occasionally occurs when skipping ahead (with the right arrow
key) while EIA-708 (ATSC) closed captions are turned on. I did some
debugging with gdb, and discovered that the crash occurs in
CC708Window::Scroll, which accesses the "text" variable even though it may
be null. I've attached a patch which adds a null check to prevent this
crash from occurring.
