Nothing comes to mind. But it explodes the same way (but without the fancy backtrace) on hurd, too. > FAIL: stunTestVectors > ===================== > > INFO | 20161218-094209.416 | | RESIP:TEST | 70366852992352 | > stunTestVectors.cxx:168 | All tests passed! > *** Error in `/«PKGBUILDDIR»/reTurn/test/.libs/stunTestVectors': double free > or corruption (out): 0x000001001be00e20 *** > ======= Backtrace: ========= > /lib/powerpc64le-linux-gnu/libc.so.6(+0x829e8)[0x3fff8ea529e8] > /lib/powerpc64le-linux-gnu/libc.so.6(+0x8c098)[0x3fff8ea5c098] > /lib/powerpc64le-linux-gnu/libc.so.6(+0x8cbec)[0x3fff8ea5cbec] > /usr/lib/powerpc64le-linux-gnu/libcrypto.so.1.0.2(CRYPTO_free+0x60)[0x3fff8ef79430] > /usr/lib/powerpc64le-linux-gnu/libssl.so.1.0.2(+0x4ded8)[0x3fff8f19ded8] > /usr/lib/powerpc64le-linux-gnu/libcrypto.so.1.0.2(sk_pop_free+0x74)[0x3fff8f0134c4] > /usr/lib/powerpc64le-linux-gnu/libssl.so.1.0.2(SSL_COMP_free_compression_methods+0x3c)[0x3fff8f1a0b6c] > /«PKGBUILDDIR»/reTurn/test/.libs/stunTestVectors(_ZNSt15_Sp_counted_ptrIPN4asio3ssl6detail17openssl_init_base7do_initELN9__gnu_cxx12_Lock_policyE2EE10_M_disposeEv+0x64)[0x5e41a044] > /«PKGBUILDDIR»/reTurn/test/.libs/stunTestVectors(_ZNSt10shared_ptrIN4asio3ssl6detail17openssl_init_base7do_initEED1Ev+0xdc)[0x5e41a41c] So a deconstructor in asio invokes SSL_COMP_free_compression_methods() on the end and we explode while the list is cleaned up. Now lets look a little… Oh what is this rutil/ssl/OpenSSLInit.cxx: | OpenSSLInit::~OpenSSLInit() | { | mInitialized = false; | ERR_remove_state(0);// free thread error queue | EVP_cleanup();// Clean up data allocated during OpenSSL_add_all_algorithms | CRYPTO_cleanup_all_ex_data(); | ERR_free_strings();// Clean up data allocated during SSL_load_error_strings | sk_SSL_COMP_free (SSL_COMP_get_compression_methods()); | | // CRYPTO_mem_leaks_fp(stderr); | cerr << "HELLO" << endl; | delete [] mMutexes; | } |(sid)bigeasy@debbuildd:/build/resiprocate-1.11.0~alpha8/reTurn/test$ ./stunTestVectors |INFO | 20161219-202446.416 | | RESIP:TEST | 140378940325248 | stunTestVectors.cxx:168 | All tests passed! |HELLO Hmmm. It gives me the impression that exploding here is what should be expected and libssl is the victim here. Sebastian
