While preparing a new ebuild for ncbi-tools++ (bug #279606) I hit two gcc crashes. This is one of them. /usr/bin/x86_64-pc-linux-gnu-g++ -c -Wall -Wno-format-y2k -pthread -pipe -msse -msse2 -msse3 -mssse3 -msse4.1 -msse4.2 -msse4 -march=native -fPIC -O9 -finline-functions -fstrict-aliasing -ffast-math -fomit-frame-pointer -DNDEBUG -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -D_MT -D_REENTRANT -D_THREAD_SAFE -I/var/tmp/portage/sci-biology/ncbi-tools++-9.0.0/work/ncbi_cxx--9_0_0/GCC463-ReleaseMTDLL64/inc -I/var/tmp/portage/sci-biology/ncbi-tools++-9.0.0/work/ncbi_cxx--9_0_0/include /var/tmp/portage/sci-biology/ncbi-tools++-9.0.0/work/ncbi_cxx--9_0_0/src/algo/blast/api/blast_seqinfosrc_aux.cpp -o blast_seqinfosrc_aux.o /var/tmp/portage/sci-biology/ncbi-tools++-9.0.0/work/ncbi_cxx--9_0_0/src/algo/blast/api/objmgr_query_data.cpp: In constructor 'ncbi::objects::CNCBIpaa_Base::CNCBIpaa_Base()': /var/tmp/portage/sci-biology/ncbi-tools++-9.0.0/work/ncbi_cxx--9_0_0/src/algo/blast/api/objmgr_query_data.cpp:464:1: internal compiler error: Segmentation fault rm .core_phi_gapalign.c .core_blast_extend.c .core_blast_diagnostics.c .core_blast_seg.c .core_hspfilter_collector.c .core_blast_engine.c .core_blast_sw.c .core_blast_posit.c .core_blast_hspstream.c .core_ncbi_math.c .core_ncbi_std.c .core_link_hsps.c .core_phi_lookup.c .core_blast_psi.c .core_pattern.c .core_blast_psi_priv.c .core_blast_tune.c .core_blast_query_info.c .core_blast_filter.c .core_hspfilter_culling.c .core_blast_message.c .core_blast_options.c .core_blast_seqsrc.c .core_split_query.c .core_blast_aascan.c .core_gencode_singleton.c .core_greedy_align.c .core_blast_parameters.c .core_blast_itree.c .core_index_ungapped.c .core_blast_dynarray.c .core_gapinfo.c .core_na_ungapped.c .core_blast_hits.c .core_phi_extend.c .core_blast_traceback.c .core_matrix_freq_ratios.c .core_blast_lookup.c .core_blast_encoding.c .core_blast_gapalign.c .core_blast_program.c .core_blast_util.c .core_blast_setup.c .core_lookup_wrap.c .core_blast_nascan.c .core_aa_ungapped.c .core_blast_nalookup.c .core_blast_aalookup.c .core_blast_stat.c .core_blast_kappa.c .core_hspfilter_besthit.c .core_lookup_util.c make[4]: Leaving directory `/var/tmp/portage/sci-biology/ncbi-tools++-9.0.0/work/ncbi_cxx--9_0_0/GCC463-ReleaseMTDLL64/build/algo/blast/api' FAILED: src/algo/blast/api/Makefile.xblast.lib make[4]: Entering directory `/var/tmp/portage/sci-biology/ncbi-tools++-9.0.0/work/ncbi_cxx--9_0_0/GCC463-ReleaseMTDLL64/build/algo/blast/api' /bin/rm -f libxblast.so .xblast.dep .libxblast.so.stamp /bin/rm -f /var/tmp/portage/sci-biology/ncbi-tools++-9.0.0/work/ncbi_cxx--9_0_0/GCC463-ReleaseMTDLL64/lib/libxblast.so /var/tmp/portage/sci-biology/ncbi-tools++-9.0.0/work/ncbi_cxx--9_0_0/GCC463-ReleaseMTDLL64/status/.xblast.dep make[4]: Leaving directory `/var/tmp/portage/sci-biology/ncbi-tools++-9.0.0/work/ncbi_cxx--9_0_0/GCC463-ReleaseMTDLL64/build/algo/blast/api' I will try to do a proper gcc.savannah.org bug report but no promises.

> gcc version 4.3.6 (Gentoo 4.3.6-r1 p1.0, pie-10.1.5) Make sure you're using right compiler. If the issue is present in 4.6.3 too please reopen this bug, with full build.log please.
this bug is about a different issue.
I was wrong
