Comment:

 Replying to [comment:25 igloo]:
 > Can you tell me how I can reproduce a problem, please?
 The problem is triggered by two flags set in ld: {{{--enable-new-dtags}}}
 and {{{--as-needed}}}.
 Both settings are not the default settings in a vanilla ld but Linux
 distributions (openSUSE in my case) change those defaults and that is the
 reason, I am still seeing a failure on openSUSE.

 To reproduce the issue:

 1. Configure ghc that {{{--enable-new-dtags}}} and {{{--as-needed}}} are
 passed to ld.

 2. Build ghc

 3. Run {{{make TEST=process001}}}
