Source: glibc
Version: 2.27-5
Severity: normal
Tags: patch
Dear Maintainer,
As on mips, hppa still requires an executable stack for syscall restarts
and signal returns. This is BZ #23174.
2.27-5 fails to build because of the following problem:
+---------------------------------------------------------------------+
| Encountered regressions that don't match expected failures. |
+---------------------------------------------------------------------+
FAIL: nptl/tst-execstack
make: *** [debian/rules.d/build.mk:115: /<<PKGBUILDDIR>>/stamp-dir/check_libc]
Error 1
Full log is here:
https://buildd.debian.org/status/fetch.php?pkg=glibc&arch=hppa&ver=2.27-5&stamp=1531930990&raw=0
The attached fix is installed on glibc trunk.
Regards,
Dave Anglin
