[Wien] seg fault in lapw1 on Opteron with PGI-6.0 / acml

[Olivier Delaire]

Dear wien2k users,

We are trying to compile wien2k-5.3 on Linux-Debian running on Opterons. 
We are using PGI-6.0 and the ACML that ships with it. The code compiles, 
and init/lapw0 work fine, but lapw1 gives a segmentation fault. We have 
tried compiling with optimization set to -O3 and -O0. Turning on the 
debug flag -g and using gdb, we get the following message indicating a 
problem in "dcopy_()":

(gdb) set args lapw1.def
(gdb) run
Starting program: /usr/use/amd64-linux/wien2kpgi6-05.3/bin/lapw1 lapw1.def

Program received signal SIGSEGV, Segmentation fault.

(gdb) q

Has anyone experienced this problem before? What are the compiling 
options recommended for linux / opteron / PGI-6 ?

Thanks in advance,
Olivier.
