Bug#794406: g++: Non-deterministic "/usr/include/c++/5/bits/basic_string.h:121:53: internal compiler error: Segmentation fault" when compiling aptitude 0.7-1
Package: g++
Version: 4:5.2.1-3
Severity: minor
Control: affects -1 src:aptitude
Hi Matthias,
I've just tried to build the upcoming aptitude 0.7-1 inside a pbuilder
chroot.
I've first recompiled the following source packages with gcc-5/5.2.1-14
respectively g++-5/5.2.1-14 and against libstdc++6/5.2.1-14 and
installed the (necessary) packages built that way:
cwidget_0.5.17-3.dsc
cppunit_1.13.2-2.dsc
ncurses_5.9+20150516-2.dsc
xapian-core_1.2.21-1.dsc
apt_1.0.9.10.dsc
I then tried to build aptitude_0.7-1.dsc (as currently in aptitude's
debian-sid branch):
nice -n15 dpkg-buildpackage -b -j5

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <file:///usr/share/doc/gcc-5/README.Bugs> for instructions.
The bug is not reproducible, so it is likely a hardware or OS problem.

I can confirm that "the bug is not reproducible": If I rerun the same
command again, it builds fine again. And running "g++ -DHAVE_CONFIG_H

../../tests/test_resolver_costs.cc" manually immediately after the
segfault worked fine as well.
Reporting it as only minor hence. I can also try to gather more of the
stuff requested in /usr/share/doc/gcc-5/README.Bugs, but only if you
consider this really as a bug and want to try digging into it. (I'm
perfectly fine if you want to postpone investigation of this bug until
after the libstdc++6 transition.)
Hardware on which this was experienced is a Lenovo Thinkpad X250 running
Debian Sid amd64 with kernel "4.1.0-trunk-amd64 #1 SMP Debian
4.1.2-1~exp1 (2015-07-11)" with an Intel(R) Core(TM) i5-5300U CPU @
2.30GHz CPU.
[reportbug-gathered stuff missing due to some recent reportbug
incompatibilities with debian-el. But I'm not writing this report inside
the chroot where this happened anyways.]
