[Bug c++/43922] New: internal compiler error: in copy_body_r, at tree-inline.c:748 when compiling with -fopenmp

["stephan dot aiche at fu-berlin dot de" <gcc-bugzilla at gcc dot gnu dot org>]

After some recent changes to our code we observed that g++ fails with ICE when
compiled with -fopenmp. The error occurs only with the 4.3.4 compiler, 4.4.1
works.

g++-4.3 -v
