Package: valgrind
Version: 1:3.5.0-2
Severity: grave
Justification: renders package unusable
Valgrind 3.5 doesn't know that mremap may move the map address anymore
which make valgrind totally unusable as soon mremap has been used,
because the mremap related errors poison the output making it pretty
much useless.
Meanwhile the following code can be used, but it's impractical as it means you
have to rebuild everything using the mremap syscall.
#include <valgrind/valgrind.h>
#include <valgrind/memcheck.h>
static inline void *
mremap_for_valgrind(void *old_address, size_t old_size, size_t new_size,
int flags)
{
void *mres = mremap(old_address, old_size, new_size, flags);
if (mres != MAP_FAILED) {
VALGRIND_MAKE_MEM_NOACCESS(old_address, old_size);
VALGRIND_MAKE_MEM_DEFINED(mres, new_size);
}
return mres;
}
#define mremap(...) mremap_for_valgrind(__VA_ARGS__)
