Bug ID: 15921
Summary: nptl/tst-cleanup2 fails on s390x and power6
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: nptl
Assignee: siddhesh at redhat dot com
Reporter: siddhesh at redhat dot com
CC: drepper.fsp at gmail dot com
The test case nptl/tst-cleanup2 fails on s390x and power6 due to instruction
sheduling in gcc. This was reported in gcc:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58034
but it was concluded that gcc is allowed to assume that the first argument to
sprintf is a character array - NULL not being a character array.
It is trivial to avoid this problem in the test case by marking the success
return value in tst-cleanup2 as volatile.
