[asterisk-bugs] [JIRA] (ASTERISK-21665) 11.4 rc1 Crash on debian/sparc with SIGBUS, Bus Error

[Walter Doekes (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-21665?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=207341#comment-207341 ] 

Walter Doekes commented on ASTERISK-21665:
------------------------------------------

For the record:
{noformat}
root at t1000:/usr/local/src/sparcbus# cat voidsize.c 
int main() {
        return sizeof(void*);
}
{noformat}
{noformat}
root at t1000:/usr/local/src/sparcbus# ./voidsize; echo $?
4
root at t1000:/usr/local/src/sparcbus# uname -a
Linux t1000 3.2.0-4-sparc64-smp #1 SMP Debian 3.2.41-2+deb7u2 sparc64 GNU/Linux
{noformat}

Notice how the void* is sized 4 and aligned on 4 byte boundaries, even though this is a 64 bit system (requiring 8-byte aligned mutexes). That's what makes {{sparc_alignment_issues_3.diff}} necessary.
