You're right -- xptinvoke seems f*cked:
<1:54pm>monet/gallatin:tests>pwd
/usr/ports/www/mozilla-devel/work/mozilla/xpcom/reflect/xptcall/tests
<1:55pm>monet/gallatin:tests>./TestXPTCInvoke
calling direct:
1 + 1 = 2
1L + 1L = 2
2 * 2 = 4
2L * 2L = 4
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55
1 + 2 = 3.000000f
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55.000000
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55.000000f
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 + 13 + 14 +115 + 16 + 17 + 18 + 19 + 20 = 210.000000f
moo cow = milk
calling via invoke:
1 + 1 = 0
1L + 1L = 0
Segmentation fault (core dumped)
I think Bernd is right too. The build stops a little earlier than
the post-build segv we've been seeing:
