Summary: gdb_server test failures on s390x
Product: valgrind
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: m...@klomp.org
Target Milestone: ---
With valgrind 3.18.1 on Fedora 34 s390x with:
glibc-2.33-20.fc34.s390x
gdb-10.2-3.fc34.s390x
gcc-11.2.1-1.fc34.s390x
binutils-2.35.2-6.fc34.s390x
I am seeing the following failures:
gdbserver_tests/hgtls (stdoutB)
gdbserver_tests/nlsigvgdb (stderr)
gdbserver_tests/nlsigvgdb (stderrB)
gdbserver_tests/nlvgdbsigqueue (stderr)
gdbserver_tests/nlvgdbsigqueue (stdoutB)
Which I don't observe on RHEL8 s390x with:
glibc-2.28-167.el8.s390x
gdb-8.2-16.el8.s390x
gcc-8.5.0-3.el8.s390x
binutils-2.30-108.el8.s390x
