I try to generate the current GCC software for my openSUSE 11.4 system. Unfortunately, I stumble on the following German message. "... /bin/sh /home/elfring/Projekte/GNU/GCC/Quellen/4.6.0/gcc/../move-if-change tmp-optionlist optionlist echo timestamp > s-options build/genhooks \ /home/elfring/Projekte/GNU/GCC/Quellen/4.6.0/gcc/doc/tm.texi.in > tmp-tm.texi gcc -g -fkeep-inline-functions -DIN_GCC -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Wold-style-definition -Wc++-compat -fno-common -DHAVE_CONFIG_H -DGENERATOR_FILE -o build/genconstants \ build/genconstants.o build/read-md.o build/errors.o ../build-x86_64-unknown-linux-gnu/libiberty/libiberty.a /bin/sh: Zeile 1: 29541 Speicherzugriffsfehler build/genhooks /home/elfring/Projekte/GNU/GCC/Quellen/4.6.0/gcc/doc/tm.texi.in > tmp-tm.texi make[3]: *** [s-tm-texi] Fehler 139 make[3]: *** Warte auf noch nicht beendete Prozesse... rm gcc.pod make[3]: Leaving directory `/home/elfring/Projekte/GNU/GCC/erzeugt/4.6.0/Auswahl/gcc' make[2]: *** [all-stage1-gcc] Fehler 2 make[2]: Leaving directory `/home/elfring/Projekte/GNU/GCC/erzeugt/4.6.0/Auswahl' make[1]: *** [stage1-bubble] Fehler 2 make[1]: Leaving directory `/home/elfring/Projekte/GNU/GCC/erzeugt/4.6.0/Auswahl' make: *** [all] Fehler 2" How can this "memory access error"/"segmentation fault" be resolved? I would like to use the configuration parameters "--enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr/local".
I assume that an output from the command "dmesg" like the following belongs to the reported situation. [37489.218661] genhooks[4926]: segfault at 60fa40 ip 000000000060fa40 sp 00007fffd3ab7bc8 error 15 in genhooks[60c000+4000]
Please provide backtraces with gdb and/or valgrind.
(In reply to comment #2) I can not generate a backtrace myself by the tool "GNU debugger" on my system at the moment because of the issue "GDB or dependency python not properly configured?". https://bugzilla.novell.com/show_bug.cgi?id=677225#c1 I have tried the build again. Now I get a result that is different from yesterday. dmesg: ...

I would like to add that the previous results come from an environment where my self-generated GNU compiler 4.52 should be usually called. I have hoped to circumvent the reported unexpected behaviour with the following configuration that specifies the tools that are provided by my Linux distribution. elfring@Sonne:~/Projekte/GNU/GCC/erzeugt/4.6.0/Auswahl3> ~/Projekte/GNU/GCC/Quellen/4.6.0/configure --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr/local CC=/usr/bin/gcc CXX=/usr/bin/g++ ... elfring@Sonne:~/Projekte/GNU/GCC/erzeugt/4.6.0/Auswahl3> echo 'erzeugen ...' && XYZ=$(date) && make -j6 V=1 > Bauprotokoll.txt 2>&1 && date && echo "gestartet: $XYZ" erzeugen ...

I can also not rebuild the previously used GNU compiler software on my openSUSE 11.4 system at the moment.

If anyone still cares, I figured out what this was, having run into it too. The clue is "bad permissions for mapped region". A look at /proc/PID/maps confirms this: the region of genhooks that contains strcpy@@GLIBC_2.2.5 is mapped without execute permission. It appears that the openSUSE 11.4 version of ld is too old for recent versions of GCC. Installing binutils 2.23.2 has fixed the problem for me.
Closing as invalid as reported updating binutils fixes the issue.
