Bug#480433: libc6.1: mkdtemp on ia64 can return xa non null pointer not pointing at the template

[Alan Bain <afrb2@debian.org>]

Package: libc6.1
Version: 2.7-10
Severity: normal

Affects IA64 only

Code like...
static char buf[20];
strcpy(buf, "/tmp/some_XXXXXX");
char * tmpname=mkdtemp(buf);

can return tmpname which is non null and for which *tmpname seg faults
because it is not a valid address i.e. it does not point at the buf.
The template will have been modified correctly to point at a unique name.
So a workaround is to add

if (!tmpname) tmpname=buf;

Bug affects latest version of f2c-20061008-1 on IA64
(to reproduce run with no arguments, call is in the set_temp_names
function)
