Further research: the LTO pass on either the affected or unaffected
installation fails if one or both .s files come from the affected installation,
but succeeds with both .s files from the unaffected installation.

Could it be specific to x86_64-linux-gnu?

Attached cgraph dump from "/usr/lib/gcc/x86_64-linux-gnu/4.5.1/lto1
-fdump-ipa-cgraph 1.o 2.o". For some reason, though, lto1 creates only one dump
file, and that only covers its first input infile.

Attached assembler files generated for 1.cpp and 2.cpp, as well as the
assembler file generated by the LTO pass. As can be seen from the latter,
_Z6callmev is referenced but not defined.
