New issue 106 by dominiqu...@gmail.com: Vim-7.3.782 crashed (core
dump) http://code.google.com/p/vim/issues/detail?id=106
Vim-7.3.782 (huge, gtk2) crashed (core dump) on Linux-x86_64. I think
I was using the netrw plugin when it crashes, but I can't remember
exactly what I did.

(gdb) p pos
$2 = (pos_T *) 0x0
It crashed at line normal.c:7555 when dereferencing pos which is NULL.
"hg annotate normal.c" shows that line normal.c:7555 was changed
in revision 4017 (i.e v7-3-763):
vimboss 7: #ifdef FEAT_FOLDING
vimboss 7: if (cap->oap->op_type == OP_NOP
bram 4017: && (pos == (pos_T *)-1 || !equalpos(old_cursor,
*pos)) vimboss 7: && (fdo_flags & FDO_MARK)
vimboss 7: && old_KeyTyped)
vimboss 7: foldOpenCursor();
vimboss 7: #endif
The line normal.c:7555 was changed in this recent patch:

updated for version 7.3.763
Problem: Jumping to a mark does not open a fold if it is in the
same line.
(Wiktor Ruben)
Solution: Also compare the column after the jump. (Christian
Brabandt) ============================================================
I can see that line normal.c:7535 in the same function is checking
whether 'pos' is NULL a few lines above at normal.c:7535, but not
at line normal.c:7555, so that looks wrong.
I don't know yet how to reproduce the bug unfortunately.
What version of the product are you using? On what operating system?
Vim-7.3.782 (huge, gtk2), Linux x86_64.
I have it crashing after having applied patches 773-782, so I have my doubts
whether the culprit is 763...
Bye, Jojo
