Hi Folks,
My application contains pure C++, Objective-C++ and Objective-C code. I
have a shared library (framework) that uses std::string. I also have code
in my main application that uses std::string. I'm seeing lots of duplicate
free warnings appearing on the console that are originating from
std::string:
Script Debugger 4(8809,0xa000cf60) malloc: *** Deallocation of a pointer
not malloced: 0xa0b03ab4; This could be a double free(), or free() called
with the middle of an allocated block; Try setting environment variable
MallocHelp to see tools to help debug
The address is always the same, and when I set a breakpoint on
malloc_printf, its always happening when std::string is freeing its initial
empty string. Here are the two stack traces I see:
#0 0x9010c187 in malloc_printf
#1 0x90005b40 in free
#2 0x06990a47 in std::string::_M_mutate
#3 0x06990f11 in std::string::assign
#0 0x9010c187 in malloc_printf
#1 0x90005b40 in free
#2 0x90b23110 in std::string::_Rep::_M_destroy
What should I do to get Xcode stop doing this?
Cheers
-Mark
