Purifying selfserv, I found several leaks of items allocated in the call to PR_Shutdown, at the end of the program. [W] MLK: Memory leak of 316 bytes from 1 block allocated in PR_Calloc [NSPR4.DLL] Distribution of leaked blocks 316 bytes from 1 block of 316 bytes (0x030cf3d8) Allocation location calloc [MSVCRT.DLL] PR_Calloc [prmem.c:484] PR_AttachThread [pruthr.c:1018] PRI_AttachThread [pruthr.c:1457] MD_CURRENT_THREAD [w95thred.c:283] PR_Lock [prulock.c:224] PR_Putfd [prfdcach.c:173] PR_FreeFileDesc [prio.c:149] PR_CleanupIO [prio.c:80] PR_Cleanup [prinit.c:453] [W] MLK: Memory leak of 44 bytes from 1 block allocated in PR_Calloc [NSPR4.DLL] Distribution of leaked blocks 44 bytes from 1 block of 44 bytes (0x03abbfb0) Allocation location calloc [MSVCRT.DLL] PR_Calloc [prmem.c:484] PRI_AttachThread [pruthr.c:1466] MD_CURRENT_THREAD [w95thred.c:283] PR_Lock [prulock.c:224] PR_Putfd [prfdcach.c:173] PR_FreeFileDesc [prio.c:149] PR_CleanupIO [prio.c:80] PR_Cleanup [prinit.c:453] [I] HIU: Handle 0x00000148, a thread, allocated in DuplicateHandle {1 occurrence} Allocation location DuplicateHandle [KERNEL32.dll] PR_MD_INIT_THREAD [w95thred.c:98] PRI_AttachThread [pruthr.c:1475] MD_CURRENT_THREAD [w95thred.c:283] PR_Lock [prulock.c:224] PR_Putfd [prfdcach.c:173] PR_FreeFileDesc [prio.c:149] PR_CleanupIO [prio.c:80] PR_Cleanup [prinit.c:453] [I] HIU: Handle 0x0000014c, a semaphore, allocated in CreateSemaphoreA {1 occurrence} Allocation location CreateSemaphoreA [KERNEL32.dll] PR_MD_INIT_THREAD [w95thred.c:102] PRI_AttachThread [pruthr.c:1475] MD_CURRENT_THREAD [w95thred.c:283] PR_Lock [prulock.c:224] PR_Putfd [prfdcach.c:173] PR_FreeFileDesc [prio.c:149] PR_CleanupIO [prio.c:80] PR_Cleanup [prinit.c:453] [I] HIU: Handle 0x00000150, a thread, allocated in DuplicateHandle {1 occurrence} Allocation location DuplicateHandle [KERNEL32.dll] PR_MD_INIT_IO [w95io.c:91] PR_InitIO [prio.c:75] PR_InitStuff [prinit.c:235] PR_ImplicitInitialization [prinit.c:255] PR_Init [prinit.c:306]

Not PR_Shutdown, rather PR_Cleanup

All but the last leak are caused by bug 218846. As for the last leak (or rather HIU), the code at PR_MD_INIT_IO [w95io.c:91] is a call to WSAStartup. So I believe the DuplicateHandle call is made by WSAStartup even though Purify doesn't show WSAStartup in the stack. Since PR_Cleanup calls WSACleanup (via _PR_CleanupBeforeExit and _PR_MD_CLEANUP_BEFORE_EXIT), the HIU looks like a bug in Winsock. So I am marking this bug as a duplicate of bug 218846. *** This bug has been marked as a duplicate of 218846 ***

I forgot to mention that the _PR_MD_INIT_IO function in w95io.c does not make any DuplicateHandle call. This is why I believe there is a missing WSAStartup call in the stack for the last HIU.
