Hi,
Lately I have been getting rather frequent crash with gvim. It seems to happen
randomly. I do have a debug info of the crash. Unfortunately I cannot find what
is causing the crash by looking at the debug info. Can anyone help me finding
the problem that made gvim crash?
Crash info:
(c70.1018): Access violation - code c0000005 (!!! second chance !!!)
eax=01cfb950 ebx=00000000 ecx=00000000 edx=00000000 esi=00000000 edi=0012e418
eip=00438bed esp=0012dab0 ebp=0012df24 iopl=0 nv up ei pl nz na pe nc

It seems that since ebx is 0, vim is trying to access zero pointer. But I
cannot find which pointer is it.
Source code where the crash happen
fc = (funccall_T *)alloc(sizeof(funccall_T));
fc->caller = current_funccal;
current_funccal = fc;
fc->func = fp;
fc->rettv = rettv;
rettv->vval.v_number = 0;
fc->linenr = 0;
fc->returned = FALSE;
fc->level = ex_nesting_level;
/* Check if this function has a breakpoint. */
fc->breakpoint = dbg_find_breakpoint(FALSE, fp->uf_name, (linenr_T)0); <---
crash here
fc->dbg_tick = debug_tick;
