Hi,
I stumbled upon this issue while working to prepare a new GDB release on a
Fedora Rawhide VM. I talked to Mark, he pointed me to this bug, and we decided
it would be a good idea to provide some information about how to reproduce it.
I found this bug while running the GDB testsuite. I had executed the whole
testsuite at one moment, and did not notice any failures related to valgrind.
Then, I had to upgrade my VM and make sure it was running the latest software
available on Rawhide. The upgrade installed the following packages:
https://people.redhat.com/sdurigan/valgrind-375171/dnf-upgrade
As you can see, the Linux kernel was upgraded (from kernel-5.1.0-1.fc31.x86_64
to kernel-5.2.0-0.rc1.git3.1.fc31.x86_64). After that, I ran the full
testsuite again, and noticed two valgrind-related tests that started failing
when they are compiled using -m32:
gdb.base/valgrind-disp-step.exp
gdb.base/valgrind-infcall.exp
They fail on upstream GDB as well, by the way. If you would like to run the
tests on your machine, you can:
1) Build GDB: https://sourceware.org/gdb/wiki/BuildingNatively
2) Run (from the build directory):
$ make check-gdb TESTS='gdb.base/valgrind-disp-step.exp
gdb.base/valgrind-infcall.exp' RUNTESTFLAGS='--target_board unix/-m32'
If you would like to see the full log that is generated when you run this
command here, you can find it here:
https://people.redhat.com/sdurigan/valgrind-375171/gdb.log
As I said, I'm using a VM running Fedora Rawhide. The list of packages I have
installed can be found here:
https://people.redhat.com/sdurigan/valgrind-375171/packages
I am able to reproduce the problem every time I run the tests.
I can provide more information if needed. Thanks!
