Testcase: audio/rhvoice It uses -std=c++03, but adding USES=compiler:c++0x doesn't select the right compiler on the mips architecture. I can't test this myself, information is based on bug#231781.
It selects gcc7 which currently doesn't work on mips.
(In reply to Yuri Victorovich from comment #0) Which is why I said reporter's patch should be used, his didn't break mips and he reported that it fixed powerpc based archs
(In reply to Nathan from comment #2) I don't feel comfortable removing -std=xx that the project sets. USES=compiler is supposed to take care of this. In this case USES=compiler doesn't select a proper compiler, but this bug is set to "Works as Intended" for some reason.
