When I lyx I simply get 'Segmentation Fault'. I have tried all of the above versions. i686-pc-linux-gnu-3.4.3-20050110 is the version of GCC I am using.

*** Bug 89208 has been marked as a duplicate of this bug. ***
would you compile lyx with CXXFLAGS="-O -pipe" and see it solves the problem?
Sorry about the duplacate post. I must have reloaded the page. I have tested Lyx-1.3.5-r2 with the flags below and it works fine. Note that r2 also does not work with my usual flag set. Do my optimization flags go to far or is Lyx just a little buggy when it comes to GCC 3.4
Sorry my mistake. It is NOT working with 3.4.3 even with the simplified flags. I will have to recompile with 3.3.4 again.
I also have this bug, but I compiled lyx with gcc-3.3.5-20050130 using both types of optimization settings in CXXFLAGS. My emerge info is below. I ran gdb on this and it seems to be font related. Here's the stack trace from gdb at the time of the SIGSEGV. I'm going to try recompiling libforms.so.1 with less aggressive optimization to see if that helps (who knows?). #0 0xb7e17467 in XFreeFontSet () from /usr/lib/libX11.so.6 #1 0x08340a90 in XNextEvent () #2 0x083412f2 in XNextEvent () #3 0x083d28a6 in XNextEvent () #4 0x083d27a3 in XNextEvent () #5 0x08264c71 in std::deque<int, std::allocator<int> >::_M_reallocate_map(unsigned, bool) () #6 0x082649d4 in std::deque<int, std::allocator<int> >::_M_reallocate_map(unsigned, bool) () #7 0x080601a2 in std::basic_string<char, std::char_traits<char>, std::allocator<char> > std::operator+<char, std::char_traits<char>, std::allocator<char> >(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) () #8 0x08060b30 in std::basic_string<char, std::char_traits<char>, std::allocator<char> > std::operator+<char, std::char_traits<char>, std::allocator<char> >(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) () #9 0x08068d9c in std::basic_stringbuf<char, std::char_traits<char>, std::allocator<char> >::~basic_stringbuf() () #10 0x0806a302 in std::string::string<char*>(char*, char*, std::allocator<char> const&) () #11 0x08067668 in std::basic_string<char, std::char_traits<char>, std::allocator<char> > std::operator+<char, std::char_traits<char>, std::allocator<char> >(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) () #12 0x083348e1 in std::deque<int, std::allocator<int> >::_M_reallocate_map(unsigned, bool) () #13 0x08334ce7 in std::deque<int, std::allocator<int> >::_M_reallocate_map(unsigned, bool) () #14 0x08332d12 in std::deque<int, std::allocator<int> >::_M_reallocate_map(unsigned, bool) () #15 0xb7f267e2 in fl_set_object_helper () from /usr/lib/libforms.so.1 #16 0x00000001 in ??

Well, I think I figured it out. My problem appears to have been that I didn't have all my fonts properly setup. The first thing I tried was running gnome-font-install as instructed within /usr/share/fonts/README.installer: gnome-font-install --debug --smart This spewed alot of output, but when I ran lyx I got the same problem. Fek. So, then I decided I needed to add the new fontpaths I had into my xorg.conf. I ran: find /usr/share/fonts/* -type d -prune | \ sed 's/^/ FontPath "/;s/$/"/;' \ >/tmp/fontdirs Then, I added replaced any existing FontPath lines in my xorg.conf with these lines. I then restarted XWindows and now lyx works like a charm! I'm guessing that the problem is that lyx discovers fonts using some technique that's aware of what's in /usr/share/fonts/ whereas the Xorg server needs you to specify fontpaths to find out about fonts.
Just looking for an update on this. 1.3.6 still has this problem and I am wondering if it is either: 1. Just me 2. Actually a font problem as the previous poster suggested. 3. Lyx will never work with GCC 3.4 If it is either 2 or 3 can the ebuild be changed to require the use of GCC 3.3 or patched to fix the font problem? For now I just keep changing GCC versions, remerging it and then changing the GCC version back after every upgrade
