I have two shared libs: lib1 and lib2. lib1 is prebuilded to lib2.
I have Class in lib1:
#include <android/log.h>
#include "stdlib.h"
#include <string>
class Foo
{
public:
Foo()
{
__android_log_print(ANDROID_LOG_VERBOSE, "Two Libs", "Foo::Foo()");
}
~Foo();
private:
std::string str;
};
destructor defined in .cpp file.
#include "first.h"
Foo::~Foo()
{
__android_log_print(ANDROID_LOG_VERBOSE, "Two Libs", "Foo::~Foo()");
}
Than I use this class in lib2:
#include <string.h>
#include <jni.h>
#include <android/log.h>
#include "first.h"
extern "C"
{
JNIEXPORT void JNICALL Java_com_example_twolibs_TwoLibs_nativeMethod( JNIEnv* env )
{
__android_log_print(ANDROID_LOG_VERBOSE, "Two Libs", "Test std::string bug 1");
Foo* newFoo = new Foo();
__android_log_print(ANDROID_LOG_VERBOSE, "Two Libs", "Test std::string bug 2");
delete newFoo;
__android_log_print(ANDROID_LOG_VERBOSE, "Two Libs", "Test std::string bug 3");
return;
}
}
log:
09-09 12:48:14.089: V/Two Libs(13512): Test std::string bug 1
09-09 12:48:14.089: V/Two Libs(13512): Foo::Foo()
09-09 12:48:14.089: V/Two Libs(13512): Test std::string bug 2
09-09 12:48:14.089: V/Two Libs(13512): Foo::~Foo()
If I delete std::string - no crash occurs. So the problem looks like in std::string destructor.
If I define class in lib2 or use it only in lib1 - no crash occurs
If I define destructor in header only - no crash occurs
I use ndk-r8b. The same problem on crystax-r7. Build on Windows via CygWin.

I tried this with NDK-r8b on cygwin, and it worked just fine, with minimal cosmetic changes. It works correctly on Andorid 2.2 with APP_STL=gnustl_static or gnustl_shared or stlport_static or stlport_shared. Note that you need to insert System.loadLibrary("gnustl_shared") or System.loadLibrary("stlport_shared") into TwoLibs.java file.
