This one looks a little tricky: tests fail on the new salmonella VM, but succeed on the current one.

On the current salmonella VM:

There probably are differences in the system package versions, but I don't know if it is relevant.

Thanks for the report. This egg relies in bvsp-spline, which in turn relies on the f2c library, so it is possible that a difference in the system libraries is the cause. Can you tell me the OS versions of the old and new machines and the versions of gcc and f2c installed?

On the current machine:

  • f2c 20100827-1
  • gcc 4.6.2

On the new machine:

  • f2c 20100827-1
  • gcc 4.6.3

The default gcc version on the new machine is actually 4.7.2, but we had to switch to 4.6.3 because 4.7.2 has what we suppose to be a code generation issue (see #916). Maybe f2c has some dependency on the default gcc version (4.7.2)?
