Comment (by fo):
There are many sources of errors for the test suite, most well known.
I will rephrase a little what is in the book, but not much.
Readline 6.x is a source of errors:
{{{
gdb.base/completion.exp: completion of field in anonymous union
https://sourceware.org/ml/gdb-patches/2011-05/msg00002.html
https://build.opensuse.org/package/view_file?file=gdb-
bz701131-readline62-2of3.patch&package=gdb&project=devel%3Agcc&rev=faca1ad22a8a7c1d46e3790a16f62e29
The suggested workaround (in fact the readline-5.1 code state) going to
patch
into the proposed FSF GDB bundled readline-6.2. Distros then can stop
using
--with-system-readline to still feature recent and system matching
readline
until readline-7.0 gets released.
Also some comments at
https://lists.gnu.org/archive/html/bug-readline/2011-04/msg00012.html
}}}
Dropping --with-system-readline switch, compared results are:
{{{

# of expected passes 27710 96,32% 27837 96,44%
# of unexpected failures 737 2,56% 709 2,46%

I will refer to original using --with-system-readline switch, in the
following.
{{{
FAIL for timeout 581 78,83%
FAIL other causes 156 21,17%
Total 737
}}}
Still more curious are same tests failing for more than one reason (this
is what I interpret, may be wrong interpretation).
Failed more than 10 times:
{{{
Test Number of failures
wp-replication.exp 94
py-inferior.exp 79
store.exp 57
py-prettyprint.exp 42
schedlock.exp 36
hand-call-in-threads.exp 33

TOTAL 621
}}}
I spent some time since yesterday or the day before (can't remember)
searching for ther errors and found with success many previous reports.
