Bug ID: 389540
Summary: KPatience: crash on exit after winning Spider
Solitaire game
Product: kpat
Version: 3.6
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: co...@kde.org
Reporter: awil...@adelielinux.org
CC: kde-games-b...@kde.org
Target Milestone: ---
Application: kpat (3.6)
(Compiled from sources)
Qt Version: 5.9.1
Frameworks Version: 5.41.0
Operating System: Linux 4.14.8-mc2-easy x86_64
-- Information about the crash:
This computer is running Adelie Linux, which uses the musl libc. The crash
occurs in musl's free() method - here is the relevant two lines from musl code:
/* Crash on corrupted footer (likely from buffer overflow) */
if (next->psize != self->csize) a_crash();
This suggests that the Spider solver had a small buffer overflow.
- What I was doing when the application crashed:
Quitting the application.
-- Backtrace:
Application: KPatience (kpat), signal: Segmentation fault
