Bad dex magic dex about mariana-trench

[Securee]

I resolved this issued by:
1、set up the development environment
2、before re-compiled the redex, add dex version 39 support in the redex\libredex\DexLoader.cpp
static void validate_dex_header(const dex_header* dh,
size_t dexsize,
int support_dex_version) {
bool supported = false;
switch (support_dex_version) {
case 39:
supported = supported ||
!memcmp(dh->magic, DEX_HEADER_DEXMAGIC_V39, sizeof(dh->magic));
case 38:
supported = supported ||
!memcmp(dh->magic, DEX_HEADER_DEXMAGIC_V38, sizeof(dh->magic));

3、modify the default support dex version to 39 in the source/MarianaTrench.cpp
void MarianaTrench::run(const program_options::variables_map& variables) {
...
context.stores = init(
boost::join(system_jar_paths, ","),
options.apk_directory(),
options.dex_directory(),
/* balloon / true,
/ support_dex_version */ 39);
4、build the mariana-trench

Redex might not support version 39. Please open an issue at https://github.com/facebook/redex
