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

On the new salmonella VM: ​http://salmonella-linux-x86.call-cc.org/master-debugbuild/gcc/linux/x86/2014/01/18/salmonella-report/test/parametric-curve.htmlz

On the current salmonella VM: ​http://tests.call-cc.org/master/linux/x86/2014/01/18/salmonella-report/test/parametric-curve.htmlz

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?

[Mario Domenech Goulart]

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)?
