I updated my portage tree to the state of 2017-12-16 and it tried to build firefox 52.5.2. This failed at some point when linking: ../../gfx/thebes/Unified_cpp_gfx_thebes1.o: In function `gfxTextRun::SetSpaceGlyph(gfxFont*, mozilla::gfx::DrawTarget*, unsigned int, unsigned short) [clone .cold.369]': Unified_cpp_gfx_thebes1.cpp:(.text.unlikely+0x7a17): undefined reference to `gfxShapedWord* gfxFont::GetShapedWord<unsigned char>(mozilla::gfx::DrawTarget*, unsigned char const*, unsigned int, unsigned int, mozilla::unicode::Script, bool, int, unsigned int, gfxTextPerfMetrics*)' /usr/lib/gcc/x86_64-pc-linux-gnu/6.4.0/../../../../x86_64-pc-linux-gnu/bin/ld: libxul.so: hidden symbol `_ZN7gfxFont13GetShapedWordIhEEP13gfxShapedWordPN7mozilla3gfx10DrawTargetEPKT_jjNS3_7unicode6ScriptEbijP18gfxTextPerfMetrics' isn't defined /usr/lib/gcc/x86_64-pc-linux-gnu/6.4.0/../../../../x86_64-pc-linux-gnu/bin/ld: final link failed: Bad value collect2: error: ld returned 1 exit status I'll attach the build log and environment.
