Hello developers:
I want to write a tool for valgrind base on memcheck. I use the '_WRAP_
macros' to wrap malloc in libc, but there show me an error:
valgrind: m_redir.c:638 (vgPlain_redir_notify_new_DebugInfo): Assertion
'is_plausible_guest_addr(sym_avmas.main)' failed.
Segmentation fault (core dumped)
The code i add to 'mc_main.c' is:
long I_WRAP_SONAME_FNNAME_ZU(libcZdsoZd6,malloc) ( long n )
{
char * r;
OrigFn fn;
VALGRIND_GET_ORIG_FN(fn);
CALL_FN_W_W(r, fn, n);
//cloak_malloc_addr = r;
return r;
}
(I has already disable the malloc replacement by deleting
vgpreload_memcheck-amd64-linux.so.)
Thanks
