Architecture: powerpc
Machine: macppc
>Description:
	It appears that during the build of lang/mono, a mono
	executable is used at some stage in the build process.

	On NetBSD/macppc 4.0, this mono invocation loops, consuming
	100% system CPU, as can be seen here:

load averages:  1.01,  1.02,  1.00                 up 84 days, 23:46   11:35:53

CPU states:  0.0% user,  0.0% nice,  100% system,  0.0% interrupt,  0.0% idle
Memory: 241M Act, 123M Inact, 4740K Wired, 52M Exec, 291M File, 1632K Free

	and in this output from "systat vm":

	This was experienced during a bulk pkgsrc build, so of course
	the build stalls at this point.

	The process which loops in this manner is running:

13413 ttyp2 RN   2290:10.59 /usr/pkgsrc/lang/mono/work/mono-2.0.1/mono/mini/mono --config /usr/pkgsrc/lang/mono/work/mono-2.0.1/runtime/etc/mono/config ./class/lib/monolite/mcs.exe /out:build/deps/basic-profile-check.exe build/deps/basic-profile-check.cs

	according to the output from "ps axww".

	A small session with gdb may point to where it's working:

    0x0 <repeats 64 times>}}
(gdb) 

	At this point I tried a "next", which appears to have been a
	bad idea: gdb appeared to hang, and when I killed gdb, it
	pulled mono with itself:

malus# kill %2
Detaching from program: /usr/pkgsrc/lang/mono/work/mono-2.0.1/mono/mini/mono, process 13413
stat 2 flag 0
Quitting: ptrace: Device busy.
sorry, pid 13413 was killed: orphaned traced process

malus# 

	Hopefully this will give someone at least some leads as to
	what the problem is.

>How-To-Repeat:
	Try to build lang/mono on NetBSD/macppc 4.0.

>Fix:
	Sorry, don't know.

 Hi,

 the attached patch makes the build complete on NetBSD/macppc
 5.0_RC3.  Looks OK to commit (modulo freeze approval)?
