Re: glib / Tru64 v.5.0 interaction bug report & workaround

[jhbrown ai mit edu (Jeremy H. Brown)]

My original report is now bugzilla bug 50532.  I'll throw this one
comment out on this list, since this is where I originally posted, and
then I'll leave it to bugzilla.

The man page for dlopen on my machine says:
------
  If neither RTLD_GLOBAL nor RTLD_LOCAL are specified, RTLD_GLOBAL will be
  assumed. However, unlike explicit use of RTLD_GLOBAL, this default mode
  will allow dynamic rebinding of symbol addresses and recalculation of
  dynamic relocations as shared libraries are loaded or unloaded.
------

>From this, I think that on this particular OS, you can safely omit
RTLD_GLOBAL -- so my inclination is to suggest that you auto-detect
tru64 unix and bind RTLD_GLOBAL to 0 in that special case.  (I think
you're almost certainly right that this is a Tru64 bug.)
