The piece of code attached to this mail does not compile with 4.3.0 20070113
(sorry this is rather old, but that's what I had available). The
architecture (although not relevant IMHO)
is i686-pc-linux-gnu.
[ Even though this is not relevant here, a similar error happens with
the redhat version gcc-4.1.1 (although the message is slightly
different and more confusing). ]
I get the following error message:
-> g++ -fopenmp Test.C
Test.C: In constructor ‘R<M>::R()’:
Test.C:18: error: invalid use of incomplete type ‘struct R<M>::R()::B’
Test.C:9: error: declaration of ‘struct R<M>::R()::B’
I really do not see why R<M>::B is considered as an incomplete type at
this point (this seems related
to the use of "typename M::E", remove the template on M and everything
works fine).
Before cluttering the bug database, can someone confirm:
1) that indeed it looks like a bug (after all, I have been wrong
before... and I'm only starting with OpenMP),
2) that it still affects mainline.
I'll try to re-test with an up-to-date compiler tonigh (svn update in
progress, but that will take some time).
Thank's
