c++ - Cocos2d-x Android project random crash libc fatal signal 11 error? -

i using cocos2d-x build both win32 , android application. met fatal problem when seek port android win32. wrote next code in android seek read file assets. but, each time android application crashes @ ccfileutils::sharedfileutils()->getfiledata. don't know why. using code in other places, , work fine.

#if cc_target_platform == cc_platform_android unsigned long size = 0; cclog("filepath name %s",filename); unsigned char* filebuff = ccfileutils::sharedfileutils()->getfiledata(filename,"rb",&size); cclog("filebuff"); ccstring* ccstr = ccstring::createwithdata(filebuff,size); cclog("ccstr end"); runscriptbuffer(ccstr->getcstring(),ret_string,name); #endif

this whole function implementation:

bool cluascriptreader::runscriptfile(const char *filename,char* ret_string,char *name){ if( m_plua == null || ret_string == null || filename == null ) homecoming false; #if cc_target_platform == cc_platform_win32 char filebuff[max_lua_file_len] = ""; char line[1024] = ""; file* fpfile = fopen(filename,"r"); if( fpfile == null ) { printf("can not find file %s\n",filename); homecoming false; } while( fgets(line, 1024, fpfile) != null) { strcat(filebuff,line); } fclose(fpfile); runscriptbuffer(filebuff,ret_string,name); #endif #if cc_target_platform == cc_platform_android unsigned long size = 0; cclog("filepath name %s",filename); unsigned char* filebuff = ccfileutils::sharedfileutils()->getfiledata(filename,"rb",&size); cclog("filebuff %l",size); ccstring* ccstr = ccstring::createwithdata(filebuff,size); cclog("ccstr end"); runscriptbuffer(ccstr->getcstring(),ret_string,name); #endif homecoming true; }

following error log got using ndk-stack tool.
