Segfault in link_to_scrollback() => free() #34

Closed dvdhrm closed 11 years ago

dvdhrm commented 11 years ago

There is some nasty bug in the TSM-screen layer. It causes a SIGSEGV in free() so there might be some random memory corruption (or double free that isn't properly detected). I cannot narrow it down but it happens when setting the "perfect" combination of a bottom-margin + reszizing often + cat /dev/urandom.

Just as reminder that we need to check that again. If someone finds a way to reliably reproduce it, I will try narrowing it down further.
