Comment # 5 on bug 921577 from Michel Normand

In my Power8 guest (started with -smp of comments #2)
I am able to recreate the failure with following steps

* the step1 + step2 is creating the problem
* the step3 is to recreate the problem after step2.

=== step1:
$osc co openSUSE:Factory:PowerPC doxygen
$cd openSUSE:Factory:PowerPC/doxygen
$quilt setup doxygen.spec
$cd doxygen-1.8.9.1
$quilt push -a
$cd ../
$mv doxygen-1.8.9.1 ~/
$cd ~/doxygen-1.8.9.1
$sed -i~ '/^TMAKE_CFLAGS_RELEASE.*/s@^.*@TMAKE_CFLAGS_RELEASE = -fmessage
length=0 -grecord-gcc-switches -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector
-funwind-tables -fasynchronous-unwind-tables -g @'
tmake/lib/linuxg++/tmake.conf
$ulimit -c unlimited
=== step2:
$./configure --prefix /usr --install /usr/bin/install && make -j4 &&
./bin/doxygen
===
=== step3:
$make clean && rm -rf doxygen_docs && rm -f doxygen.tag
$./configure --prefix /usr --install /usr/bin/install && make -j4 &&
./bin/doxygen
===


The generated core file and gdb gives the following backtrace:
===
$gdb -c ./core ./bin/doxygen
...
Core was generated by `./bin/doxygen '.
