--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Please reduce first the objects needed to reproduce the ICE:
- you can add them to files.txt files and then use cvise-delta:
g++ @files.txt ... 2>&1 | grep 'internal com..'

Then you can create pre-processed source files for the problematic objects.
And finally, you can reduce these (cvise can reduce more files in parallel).

I cannot reproduce it in openSUSE:Factory.

--- Comment #2 from Matthias Klose <doko at debian dot org> ---
the compiler is configured with --enable-default-pie.

so this one sometimes fails with different reasons when retrying:

lto1: error: filter/andfiltertest.o: file too short
lto1: fatal error: errors during merging of translation units
compilation terminated.
lto-wrapper: fatal error: g++ returned 1 exit status
compilation terminated.
/usr/bin/ld: error: lto-wrapper failed
collect2: error: ld returned 1 exit status

and doesn't fail now when just retrying the link command manually now ...

these flags are passed to the upstream build system:

CFLAGS=-g -O2 -ffile-prefix-map=/packages/tmp/log4cxx-0.11.0=. -flto=auto
-ffat-lto-objects -fstack-protector-strong -Wformat -Werror=format-security
CPPFLAGS=-Wdate-time -D_FORTIFY_SOURCE=2
CXXFLAGS=-g -O2 -ffile-prefix-map=/packages/tmp/log4cxx-0.11.0=. -flto=auto
-ffat-lto-objects -fstack-protector-strong -Wformat -Werror=format-security
LDFLAGS=-flto=auto -Wl,-z,relro
