We are trying to track down a numerical problem with unuran that

gcc-4.3. I know that gcc now has a very extensive test suite, and bugs are
not common. I'm just wondering, are others finding similar problems with
gcc-4.3?
We are working on preparing a bug report. The symptoms are:
1) Problem disappears if -O0
2) Problem disappears if a printf is added
That probably means there is a problem with the memory layout (something
stomping on your variables?).
What hapens if you call any other function instead of printf?
Have you tried to look at the generated assembly?
3) valgrind is silent
