Hi everyone,

I gave this a try with DBT-2, but got a core dump on our ia64 system.
I hope this isn't a random thing, like I ran into previously.  Maybe
I'll try again, but postgres dumped core.  Binary and core here:
	http://developer.osdl.org/markw/pgsql/core/2morefiles.tar.bz2

#0  FunctionCall2 (flinfo=0x0, arg1=0, arg2=0) at fmgr.c:1141
1141            result = FunctionCallInvoke(&fcinfo);
(gdb) bt
#0  FunctionCall2 (flinfo=0x0, arg1=0, arg2=0) at fmgr.c:1141
#1  0x40000000003bdb80 in FunctionCall2 (flinfo=Cannot access memory at address 0x0
) at fmgr.c:1141
#2  0x40000000003bdb80 in FunctionCall2 (flinfo=Cannot access memory at address 0x0
) at fmgr.c:1141

Over and over again, so I'll keep the backtrace short.

Mark
