Installed gnat-gcc-4.4.5. Have eselect-gnat-1.5 installed FWIW. Tried to compile a simple hello world program (i.e. gnatmake hello_world_1.adb). The compilation fails during linking with the following errors gnatbind -x hello_world_1.ali gnatlink hello_world_1.ali /usr/lib64/gnat-gcc/x86_64-pc-linux-gnu/4.4/adalib/libgnat.a(a-finali.o): In function `ada__finalization___assign__3': (.text+0x21e): undefined reference to `_Unwind_Resume' : : etc. Reproducible: Always Tried to roll back to gnat-gcc-4.4.3 and 4.3.5, but those ebuilds don't appear to bootstrap.
If I tell the linker to link against the c++ std library, i.e. >gnatmake hello_world.adb -largs -lstdc++ then i get what appears to be a working program. This does not feel like the right fix for this.
Did a reinstall just to see what would happen, and I no longer have this issue.
