>Description:
I just noticed that -current, with COMPAT_OSF1 cannot run dynamic Tru64
executables, while static ones have no problems. The problem seems to be
that it cannot find the run-time loader anymore (installed from pkgsrc
emulators/osf1_lib package)..

A simple `Hello World' program exhibit the problem.

njoly@thanos [~]> file ./hello
hello: ECOFF alpha demand paged not stripped - version 2864.
njoly@thanos [~]> ktrace -di ./hello
ktrace: exec of './hello' failed: No such file or directory
njoly@thanos [~]> kdump | head
   761      1 ktrace   EMUL  "netbsd"
   761      1 ktrace   CALL  execve(0x1fffffd9b,0x1ffffdbb0,0x1ffffdbc0)
   761      1 ktrace   NAMI  "./hello"
   761      1 ktrace   NAMI  "/emul/osf1"
   761      1 ktrace   NAMI  "/emul/osf1/sbin/loader"
   761      1 ktrace   NAMI  "/sbin/loader"
   761      1 ktrace   RET   execve -1 errno 2 No such file or directory
   761      1 ktrace   CALL  write(2,0x1ffffd490,8)
   761      1 ktrace   GIO   fd 2 wrote 8 bytes

njoly@thanos [~]> file /emul/osf1/sbin/loader
/emul/osf1/sbin/loader: ECOFF alpha demand paged stripped - version 2816.

The same program statically compiled, works flawlessly.

njoly@thanos [~]> file ./hello2 
hello2: ECOFF alpha demand paged not stripped - version 2816.
njoly@thanos [~]> ./hello2 
Hello World

>How-To-Repeat:
Try to run any dynamic Tru64 executable under COMPAT_OSF1.

n/a
