There are some warnings concerning pointers. A
  cat nohup.out | grep -A 5 -B 5 "incompatible pointer"
gives:

Further warnings
================

These should be observable on any platform.

- _configtest.c: the usual warnings

- gcc: scipy/corelib/mtrand/mtrand.c
  scipy/corelib/mtrand/mtrand.c:
  In function `__pyx_tp_new_6mtrand_RandomState':
  scipy/corelib/mtrand/mtrand.c:4908: warning: unused variable `p'
- warning: callstatement is defined without callprotoargument

                              rwork,iwork,mf,
                              [f_extra_args,jac_extra_args,overwrite_y])
  Wrote C/API module "vode" to file "build/src/Lib/integrate/vodemodule.c"

- many "might be used uninitialized"
  (I don't like that, but OTOH it means to look into oldish
   Fortran code. Not sure if this is worth the effort ..)

  Concerns: dfftpack,quadpack,odepack,amos,toms,cdflib,
            specfun,minpack,fitpack, ...

- Lib/special/cephes/sincos.c:232: warning:
  conflicting types for built-in function 'sincos'

- SuperLU seems to be in bad shape:
  *many* implicit declarations like:
    Lib/sparase/SuperLU/SRC/clacon.c:150:
    warning: implicit declaration of function `ccopy_'
  many "suggest parentheses around assignment used as truth value"

- several warnigns in:

  build/src/Lib/linalg/iterative/BiCGREVCOM.f: In subroutine
`sbicgrevcom':
  build/src/Lib/linalg/iterative/BiCGREVCOM.f:135: warning:
            IF (RLBL .eq. 2) GOTO 2
                                  1
