+   The bug here was that we had a line like:
+       # 33554432 "../../gcc/testsuite/gcc.dg/cpp/pragma-3.c"
+   
+   Before line:
+
+       #pragma omp parallel private (i1) shared (j1) firstprivate (k1)
+
+   Note the very big integer there.  Normally we should just have
+   this:
+   
+       # 13 "../../gcc/testsuite/gcc.dg/cpp/pragma-3.c"
+       #pragma omp parallel private (i1) shared (j1) firstprivate (k1)
+
+   So let's check that we have no line with a number of 3 or more
+   digit after #:
+
+   { dg-final { scan-file-not pragma-3.i "# \[0-9\]{3} \[^\n\r\]*pragma-3.c" } }
