[petsc-dev] variable 'length' is uninitialized in src/sys/fileio/mprint.c

[Vaclav Hapla]

Barry,
this is obviously wrong in current master:

14416c0e507 src/sys/fileio/mprint.c     791)     size_t length;
cb500232d0b src/sys/fileio/mprint.c     792)     char   buff[length];

It results in
  warning: variable 'length' is uninitialized when used here [-Wuninitialized]
when the PETSC_HAVE_MATLAB_ENGINE macro is defined.
