I tried gcc 4.4.0 20080613 (experimental):
indeed, it works now!

This appears to work for me now with
  gcc version 4.4.0 20080527 (experimental) [trunk revision 136055] (GCC) 
Can you check whether it also works for you?

W.

The bug ist still present in gcc 4.3.0:

bug.cpp:16: internal compiler error: in create_tmp_var, at gimplify.c:497

Here is a self-contained example:

templateclass T, int Sz
class Vector {
public:
  explicit Vector() {}
  ~Vector() {}
private:
  T m_data[Sz];
};

int main() {
  Vectorint,3 a[10];
  int i;
#pragma omp parallel
  {
#pragma omp for schedule(dynamic)
for (i=0; i10; ++i) {
  // do something
}
#pragma omp master
{
a[0] = a[1];
}
#pragma omp for schedule(dynamic)
for (i=0; i10; ++i) {
  // do something
}
  }
}

I can avoid the internal compiler error by:
 1) removing the '-fopenmp' option
 2) changing the '#pragma omp' statements as shown in the original example
 3) removing the destructor '~Vector() {}' from 'class Vector' in the new
example!

Can you try to come up with an example that is self-contained,
i.e. only contains those parts of the Tiny Vector Matrix library
that are really used (or none at all)?
