Hi Marco,
freeing an address that is not alligned to typically 4 or 8 bytes is
never possible,
because malloc would never return such.
Your pointer ends with 0x..1 so it cannot be alligned on any architecture.

I know. The application is crashing.
It is clearly a free call with a corrupted pointer,
but not knowing the caller address make difficult to
identify what is corrupting the pointer.
Your Post:
Debugging a program I am trying to catch where this call is happening
17 1499678 [main] ncview 1484 free: (0x6000D7961), called by 0x180115A0B
unfortunately the 0x180115A0B address is not real caller address
/usr/src/debug/cygwin-1.7.33-1/winsup/cygwin/malloc_wrapper.cc
extern "C" void
free (void *p)
{
malloc_printf ("(%p), called by %p", p, __builtin_return_address (0));
if (!use_internal)
user_data->free (p);
else
{
__malloc_lock ();
dlfree (p);
__malloc_unlock ();
}
}
Any way to improve the tracing ?
