Subject: exec.c: Initialize sa_flags passed to sigaction()
X-Git-Tag: v3.0.0-rc0~117^2~22
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8347c18506c3f8619527d19134cb4aac071dc54a;p=thirdparty%2Fqemu.git

exec.c: Initialize sa_flags passed to sigaction()

Coverity points out that in the user-only version of cpu_abort() we
call sigaction() with a partially initialized struct sigaction
(CID 1005351). Correct the omission.
