[Bsd-sharp-list] make hangs with mini/mono taking 100% CPU

[Steve McLellan]

Hi,

Apologies in advance; I'm not a particularly BSD-savvy chap. I'm trying
to build mono on a BSD 6.2 box. It gets to the following line before
hanging.

gmake[5]: Entering directory
`/var/ports/usr/ports/lang/mono/work/mono-1.2.5/mcs'

The process list shows the following taking up 100% CPU (it ran for 15
minutes before I killed it):

/var/ports/usr/ports/lang/mono/work/mono-1.2.5/mono/mini/mono --config
/var/ports/usr/ports/lang/mono/work/mono-1.2.5/runtime/etc/mono/config
./class/lib/monolite/mcs.exe  /out:build/deps/basic-profile-check.exe
build/deps/basic-profile-check.cs

Stack trace in gdb shows:

It appears to be a threading issue. Someone here suggested putting the
following in /etc/libmap.conf but it didn't have any appreciable effect.
[/var/ports/usr/ports/lang/mono/work/mono-1.2.5/mono/mini/mono]
libpthread.so.2         libthr.so.2
libpthread.so           libthr.so

Are there any kernel options that you know of that could cause this kind
of problem?

Thanks,

Steve
