Tested with current git, both Mesa and complete X environment. Valgrind shows few warnings when running the test case, and seems to freeze (100% CPU). It probably has to emulate and verify a lot of memory accesses, or I hit a bug in valgrind: ==15227== ==15227== Syscall param writev(vector[...]) points to uninitialised byte(s) ==15227== at 0x4260492: do_writev (in /lib/libc-2.5.so) ==15227== by 0x81B5A7D: _XSERVTransSocketWritev (Xtranssock.c:2192) ==15227== by 0x81B477E: _XSERVTransWritev (Xtrans.c:914) ==15227== by 0x81AF969: FlushClient (io.c:1057) ==15227== by 0x81B00F3: FlushAllOutput (io.c:809) ==15227== by 0x808901E: Dispatch (dispatch.c:525) ==15227== by 0x80707A4: main (main.c:469) ==15227== Address 0x63FAB3C is 36 bytes inside a block of size 4,096 alloc'd ==15227== at 0x40233F0: malloc (in /usr/lib/valgrind/x86-linux/vgpreload_memcheck.so) ==15227== by 0x81B1C96: Xalloc (utils.c:1351) ==15227== by 0x81AF596: AllocateOutputBuffer (io.c:1197) ==15227== by 0x81AFE3F: WriteToClient (io.c:916) ==15227== by 0x8082626: SendConnSetup (dispatch.c:3940) ==15227== by 0x808273F: ProcEstablishConnection (dispatch.c:3988) ==15227== by 0x8088FBE: Dispatch (dispatch.c:503) ==15227== by 0x80707A4: main (main.c:469) Cleaning up stray priv pointers to 0x661ef28 in context 0x63fcac0 Cleaning up stray xmesa pointers to buffer 0x6a4e5c8 in context 0x63fcac0 ==15227== Warning: set address range perms: large range 134217728 (undefined) -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------------------------- Take Surveys.
