I am creating a C++ program that embeds Spidermonkey JS library. The program is running fine but it it is leaking memory in JS_NewRuntime call with more than one thread. It is leaking 32 bytes per thread.
Spidermonkey JS version : 45 NSPR version: 4.15 Sample program attached(sample.cpp): // following code might be needed in some case #define __STDC_LIMIT_MACROS #include <stdint.h> #include "nspr/prthread.h" #include "nspr/prinit.h" #include "jsapi.h" #include "js/Initialization.h" /* The class of the global object. */ static JSClass global_class = { "global", JSCLASS_GLOBAL_FLAGS, nullptr, nullptr, nullptr, nullptr, nullptr, nullptr, nullptr, nullptr, nullptr, nullptr, nullptr, JS_GlobalObjectTraceHook }; static void CreateThreads(void *); int main(int argc, const char *argv[]) { JS_Init(); PRThread* Thread[5]; for(int i=0; i<5; i++) Thread[i] = PR_CreateThread(PR_USER_THREAD, &CreateThreads, NULL,PR_PRIORITY_NORMAL, PR_GLOBAL_THREAD, PR_JOINABLE_THREAD, 0); for(int i=0; i<5; i++) PR_JoinThread(Thread[i]); JS_ShutDown(); return 0; } void CreateThreads(void *arg) { JSRuntime *rt = JS_NewRuntime(8L * 1024 * 1024); if (!rt) return ; JS_DestroyRuntime(rt); } Command to compile: g++ --std=c++11 -DDEBUG -o a.out sample.cpp -I./include -Llib -lmozjs-45 -lpthread -lnspr4 Command to execute: LD_LIBRARY_PATH=lib/ valgrind --leak-check=full --log-file=./leak.log ./a.out Valgrind Stacktrace: 128 bytes in 4 blocks are definitely lost in loss record 39 of 59 ==13653== at 0x4C27BE3: malloc (vg_replace_malloc.c:299) ==13653== by 0x5753B86: js_malloc(unsigned long) (Utility.h:221) ==13653== by 0x5757FF3: _Z6js_newIN4nspr6ThreadEIDnS2_bEEPT_DpOT0_ (Utility.h:333) ==13653== by 0x575578F: PR_GetCurrentThread() (PosixNSPR.cpp:146) ==13653== by 0x575F6ED: JSRuntime::init(unsigned int, unsigned int) (Runtime.cpp:265) ==13653== by 0x54BE53C: JS_NewRuntime(unsigned int, unsigned int, JSRuntime*) (jsapi.cpp:469) ==13653== by 0x4009EB: CreateThreads(void*) (in /vagrant/sandhya_workspae/t/jssample_new/a.out) ==13653== by 0x6CCD5A9: _pt_root (ptthread.c:216) ==13653== by 0x6A82DC4: start_thread (in /usr/lib64/libpthread-2.17.so) ==13653== by 0x77FF73C: clone (in /usr/lib64/libc-2.17.so) _______________________________________________ dev-tech-js-engine-internals mailing list dev-tech-js-engine-internals@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-tech-js-engine-internals
