Hi
First please CC to me as I am not on the hackers mail list.
I am trying to get the ORBacus working for FreeBSD. I know you already have
a port of ORBacus, but that is version 3, and their latest release is version
4. In order to get ORBacus working to it I first need to get their JTC
library working (JTC is a thin wrapper to pthread).
Now that the user threads have re-written I was hoping to get the JTC
library to compile and work under the 4.1 kernel. I have managed to
get it to compile, but it core dumps very early in the start up code of
my application.
I have written a little simple program (attached with its Makefile) that also
exhibits the same problem. When I run the program I see the following
error reported from gdb:
(gdb) run
Starting program: nod
Program received signal SIGSEGV, Segmentation fault.
0x280747b8 in pth_cancel_point () from /usr/local/lib/libpthread.so.13
(gdb)
Can anyone offer any advice.
Steve

People don't usually make the same mistake twice -- they make it three
times, four time, five times...
