From fbef86fd7c6f53ccc77e59d2d076aa3015e83472 Mon Sep 17 00:00:00 2001 From: "A. Wilcox" Date: Fri, 9 Aug 2019 07:21:00 +0000 Subject: user/gwenview: fix stack size overflow When opening a .CR2 Canon RAW image, attempting to load the embedded preview for the thumbnail bar would result in a segmentation fault on at least x86_64, with the backtrace: Thread 4 "Thread (pooled)" received signal SIGSEGV, Segmentation fault.

Bumping the per-thread stack size to 1 MiB fixes this for all .CR2 files I have access to. --- user/gwenview/APKBUILD | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) (limited to 'user/gwenview') diff --git a/user/gwenview/APKBUILD b/user/gwenview/APKBUILD index 78cfc1858..92ecae330 100644 --- a/user/gwenview/APKBUILD +++ b/user/gwenview/APKBUILD @@ -2,7 +2,7 @@ # Maintainer: A.
