Hi,

I just installed NetBSD -current on a PWS500au i recently got :

njoly@thanos [~]> uname -a
NetBSD thanos.sis.pasteur.fr 2.0C NetBSD 2.0C (GENERIC) #3: Wed Apr  7 17:50:19 CEST 2004  njoly@thanos.sis.pasteur.fr:/local/src/NetBSD/obj/alpha/sys/arch/alpha/compile/GENERIC alpha

Everything was fine ... But i got a uvm_map assertion panic while
trying OSF1 compat with the following simple code, compiled on an
another PWS500au running Compaq Tru64 v5.1A.

NB: the same program, if statically compiled on Tru64, works fine on
NetBSD.

njoly@medusa [tmp/dec]> uname -a
OSF1 medusa.sis.pasteur.fr V5.1 1885 alpha
njoly@medusa [tmp/dec]> cat hello.c 
#include <stdio.h>

int main(int argc, char **argv) {

  printf("Hello World.\n");

  return 0; }
njoly@medusa [tmp/dec]> cc -o hello hello.c 

Copied on NetBSD alpha ...

njoly@thanos [~]> uname -a
NetBSD thanos.sis.pasteur.fr 2.0C NetBSD 2.0C (GENERIC) #3: Wed Apr  7 17:50:19 CEST 2004  njoly@thanos.sis.pasteur.fr:/local/src/NetBSD/obj/alpha/sys/arch/alpha/compile/GENERIC alpha

Is this a known problem ?

Thanks in advance,
