I wrote a Fortran to C++ conversion program that I used to convert selected
LAPACK sources. Comparing runtimes with different compilers I get:

for info.index_expr to become invalid.
For example:

Hello!
A problem arises with the code in testsuite/g++.dg/cpp0x/rv[1..8]p.C.
These tests use "sizeof(..character array...) == ", but sizeof char
array depends heavily on the value of #define STRUCTURE_SIZE_BOUNDARY.
Targets that define this value to i.e. 32 (for performance reasons,
instead of def
