[PATCH 07/17] gfortran: Avoid freeing uninitialized value

[Martin Jambor]

Hi,

When compiling fortran/match.cc, clang emits a warning

  fortran/match.cc:5301:7: warning: variable 'p' is used uninitialized whenever 
'if' condition is true [-Wsometimes-uninitialized]

which looks accurate, so this patch adds an initialization of p to
avoid the use.

Bootstrapped and tested on x86_64-linx.  OK for master?

Thanks,

Martin
