When the modified rpctrace (rpctrace.c) in the attachment traces the test program (tmp.c), which is also in the attachment, rpctrace exits unexpectedly and GNUMach crashes along with it.

The trace after Mach crash is as follows:
(null):/boot# addr2line -e gnumach-dbg 0x1036c4 0x127881 0x103b62 0x1033a4 0x11b0d1 0x11a506 0x11a4a0 0x122f6f 0x120920 0x1207ea 0x11a33d 0x11a366
