This segfault probably only happened when having MALLOC_PERTURB_ set.  Which I have.  To something random per session.

When having in your .nanorc the line 'extendsyntax c linter gcc -fshow-column', nano will segfault when aborting the linter.

To reproduce, do 'export CFLAGS='-g -Os', run './configure --disable-libmagic' and 'make clean all'.

Then run 'src/nano src/winio.c', and type ^T.  It will say: "This message is for unopened file src/nano.h, open it in a new buffer?" Type ^C.  Result: Segmentation fault.

Bug is present since nano-2.3.3.
