I've just tried to compile LibreOffice 4.0.0.2 and it crashes right after startup. Debugging shown that it is caused by callVirtualMethod in libgcc3_uno.so. The reason is that this library must be compiled with -fno-omit-frame-pointer option, but gentoo flags are added _after_ default compile flags. I think, this is not actually Gentoo bug, but for now it could be good to filter -fomit-frame-pointer for libreoffice builds. -------------------------------------------- emerge --info output: Portage

I have to thank you for this report. I was trying for days to debug this, without success. Libreoffice uses exceptions and I was able to dig out that an exception was thrown during removing of old temporary directory, during the start sequence, and that exception handling triggered segfault. I can confirm that rebuilding without -fomit-frame-pointer fixes the problem.
Apparently upstream knows about this [1]. So, building without -fomit-frame-pointer is a good temporary solution, but let's make sure we don't filter this flag globally in the ebuild as a workaround which would be silly. This would needlessly slow down libreoffice on those old x86 machines which are register starved. Fixing the gb_Library_add_cxxflags calls in the bridges/*.mk files is the right way to go. Thanks Alexander for finally finding the root cause of bug #451778. Denis. [1] http://nabble.documentfoundation.org/gmake-CXXFLAGS-override-gb-Library-add-cxxflags-td4027995.html
4.0.1 in main tree so closing this as fixed.
