--- Comment #3 from marc.bessieres@gmail.com --- Created attachment 50140 --> https://bugs.winehq.org/attachment.cgi?id=50140 fix for definitely lost in testAddCert

Hi Austin,

In attachment I put a patch for the definite leak you reported: Also a definite leak: ==17318== 48 bytes in 1 blocks are definitely lost in loss record 159 of 334 ==17318== at 0x7BC4C6B7: notify_alloc (heap.c:255) ==17318== by 0x7BC50EFB: RtlAllocateHeap (heap.c:1716) ==17318== by 0x4EE398B: CryptMemAlloc (main.c:124) ==17318== by 0x4EBE5A6: Context_CreateLinkContext (context.c:60) ==17318== by 0x4EAAB00: Cert_clone (cert.c:127) ==17318== by 0x4EBD199: CRYPT_CollectionCreateContextFromChild (collectionstore.c:85) ==17318== by 0x4EBD485: CRYPT_CollectionAdvanceEnum (collectionstore.c:174) ==17318== by 0x4EBD6EE: Collection_enumCert (collectionstore.c:247) ==17318== by 0x4F05CB9: CertEnumCertificatesInStore (store.c:946) ==17318== by 0x4EAE3F7: cert_compare_certs_in_store (cert.c:1528) ==17318== by 0x4EAEF02: CertFindCertificateInStore (cert.c:1794) ==17318== by 0x4EAAD3C: add_cert_to_store (cert.c:192) ==17318== by 0x4EAB27F: CertAddCertificateContextToStore (cert.c:287) ==17318== by 0x4CC9B54: testAddCert (cert.c:306) ==17318== by 0x4CD8F2F: func_cert (cert.c:3976) ==17318== by 0x4D33F67: run_test (test.h:584) ==17318== by 0x4D34356: main (test.h:654)

The problem was that CertFindCertificateInStore was not called for a variable allocated with CertFindCertificateInStore.

If you have some time could you check if it works for you? And also could you check if the patch seems correct?

Cheers, Marc

Hi Marc,

Sorry I missed this (years!) ago. With wine-4.0-rc2 and valgrind-3.14.0.GIT-1d42a625ab-20181106, I currently see two potential leaks:

==20768== 20 bytes in 1 blocks are possibly lost in loss record 111 of 601 ==20768== at 0x7BC483AD: notify_alloc (heap.c:260) ==20768== by 0x7BC4B8D1: RtlAllocateHeap (heap.c:1726) ==20768== by 0x4DF6FEA: CryptMemAlloc (main.c:133) ==20768== by 0x4DD8979: CertAddStoreToCollection (collectionstore.c:518) ==20768== by 0x4E11BF3: CRYPT_SysOpenStoreW (store.c:586) ==20768== by 0x4E118A7: CertOpenStore (store.c:900) ==20768== by 0x4C22CDC: testGetIssuerCert (cert.c:1739) ==20768== by 0x4C2A940: func_cert (cert.c:4073) ==20768== by 0x4C6E986: run_test (test.h:617) ==20768== by 0x4C6F3C4: main (test.h:701)

==20768== 48 bytes in 1 blocks are possibly lost in loss record 245 of 601 ==20768== at 0x7BC483AD: notify_alloc (heap.c:260) ==20768== by 0x7BC4B8D1: RtlAllocateHeap (heap.c:1726) ==20768== by 0x4DF6FEA: CryptMemAlloc (main.c:133) ==20768== by 0x4DD8BC8: Context_CreateDataContext (context.c:32) ==20768== by 0x4DCB4D9: Cert_clone (cert.c:141) ==20768== by 0x4E1085F: MemStore_addContext (store.c:151) ==20768== by 0x4E10A41: MemStore_addCert (store.c:243) ==20768== by 0x4DCD500: add_cert_to_store (cert.c:269) ==20768== by 0x4DCD801: CertAddCertificateContextToStore (cert.c:293) ==20768== by 0x4C22B9E: testGetIssuerCert (cert.c:1721) ==20768== by 0x4C2A940: func_cert (cert.c:4073) ==20768== by 0x4C6E986: run_test (test.h:617) ==20768== by 0x4C6F3C4: main (test.h:701) ==20768==

While your patch cleanly applies (with some offsets), it doesn't seem to make a difference. From a quick glance, it doesn't look like it affects these code paths (though parts close to it).
