c++ - Visual studio to gcc, code compiles well in gcc but gives std::badalloc error at runtime -

-

i have big code uses standard c++ libs , compiles in gcc. code written in vs c++ 6.0. code runs fine in visual studio when use gcc compiler gives no errors on compilation , when run it gives error "terminate called after throwing exception @ instance std::bad_alloc what() bad alloc" 1 more confusion is numerical simulation code, doesn't show exception while using gdb debugging , terminates doesn't show right results. using gdb doesn't terminates anywhere. thats stuck. unable diagnose bad_alloc happening.

  1. the code consists of c , c++ routines
  2. memory allocated through new
  3. gdb doesn't show segabort or exception during debugging

how can debug problem?

if you're on linux, give valgrind try debugging.

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
