ID: 15316 Comment by: [EMAIL PROTECTED] Reported By: [EMAIL PROTECTED] Status: Open Bug Type: InterBase related Operating System: Linux 2.4.17-xfs PHP Version: 4.1.1 New Comment:
I wonder if this could be related to a problem I ran into, detailed at http://bugs.php.net/bug.php?id=18744 Basically, I discovered that if you tried to use ibase_blob_add to add > 64k of data to a blob at any one time, the data would be truncated. Wonder if some variation of this bug causes a core dump? Are your images > 64k in size? Previous Comments: ------------------------------------------------------------------------ [2002-08-09 13:26:10] [EMAIL PROTECTED] I am using php 4.2.2 on freebsd 4.6 and it core dumps whenever I try to insert ot update a blob in an interbase db as well. (not running from apache running the cgi version from a shell). ------------------------------------------------------------------------ [2002-03-11 20:26:44] [EMAIL PROTECTED] Does any of this information help? I see that there are now others reporting this bug, so perhaps it can be combined with those. ------------------------------------------------------------------------ [2002-02-21 20:46:50] [EMAIL PROTECTED] Well, I got pretty close to getting a backtrace, but ran across what appears to be a bug in gdb. Either that, or I am just not finding the proper documentation. I can get a gdb attached to the proper thread, via: /usr/sbin/apache.dbg gdb /usr/sbin/apache.dbg (gdb) attach <pid> (gdb) continue but when I "continue" it, it gives me a message like "Cannot find thread 2049: invalid thread handle". Now, I may be doing something wrong, but I sure can't tell what. ------------------------------------------------------------------------ [2002-02-21 18:59:10] [EMAIL PROTECTED] Incidentally, I have tried every which way to get a core dump, but even after running apache on port 1025 as a non-root user, and checking permissions on the CoreDumpDirectory, no core file is created. So, I tried attaching gdb to specific processes, but for some reason, when I attach gdb to a particular process, the process no longer accepts connections. Any hints? ------------------------------------------------------------------------ [2002-02-21 17:55:53] [EMAIL PROTECTED] Still unable to generate a backtrace, but running strace reveals this: [pid 27126] recv(5, "\0\0\0\t\377\377\377\377\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 8192, 0) = 32 [pid 27126] semop(32769, 0xbfffb5f8, 2) = 0 [pid 27126] semop(32769, 0xbfffb5fc, 1) = 0 [pid 27126] send(5, "\0\0\0C\0\0\0\5\0\0\0\2", 12, 0) = 12 [pid 27126] select(6, [5], NULL, NULL, {60, 0}) = 1 (in [5], left {60, 0}) [pid 27126] recv(5, "\0\0\0\t\377\377\377\377\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 8192, 0) = 32 [pid 27126] semop(32769, 0xbfffb5f8, 2) = 0 [pid 27126] semop(32769, 0xbfffb5fc, 1) = 0 [pid 27126] open("/www/heritage.legacyunlimited.com/pages/footer.php", O_RDONLY|O_LARGEFILE) = 8 [pid 27126] getcwd("/www/heritage.legacyunlimited.com/pages/customize", 4095) = 50 [pid 27126] lstat64("/www", {st_mode=S_IFDIR|0775, st_size=4096, ...}) = 0 [pid 27126] lstat64("/www/heritage.legacyunlimited.com", {st_mode=S_IFDIR|0775, st_size=156, ...}) = 0 [pid 27126] lstat64("/www/heritage.legacyunlimited.com/pages", {st_mode=S_IFDIR|0775, st_size=4096, ...}) = 0 [pid 27126] lstat64("/www/heritage.legacyunlimited.com/pages/footer.php", {st_mode=S_IFREG|0664, st_size=4322, ...}) = 0 [pid 27126] ioctl(8, SNDCTL_TMR_TIMEBASE, 0xbfffb67c) = -1 EINVAL (Invalid argument) [pid 27126] fstat64(8, {st_mode=S_IFREG|0664, st_size=4322, ...}) = 0 [pid 27126] old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40277000 [pid 27126] read(8, "<?\n/* OLD COPYRIGHT LINKS---\nAc"..., 8192) = 4322 [pid 27126] read(8, "", 4096) = 0 [pid 27126] read(8, "", 8192) = 0 [pid 27126] ioctl(8, SNDCTL_TMR_TIMEBASE, 0xbfffa658) = -1 EINVAL (Invalid argument) [pid 27126] close(8) = 0 [pid 27126] munmap(0x40277000, 4096) = 0 [pid 27126] munmap(0x403a1000, 94208) = 0 [pid 27126] chdir("/") = 0 [pid 27126] send(6, "\0\0\0\25\0\0\0\0", 8, 0) = 8 [pid 27126] select(7, [6], NULL, NULL, {60, 0}) = 1 (in [6], left {60, 0}) [pid 27126] recv(6, "\0\0\0\t\0\0\0\0\0\0\0\0@3\256L\0\0\0\0\0\0\0\1\0\0\0\0"..., 8192, 0) = 32 [pid 27126] send(6, "\0\0\0\6", 4, 0) = 4 [pid 27126] shutdown(6, 2 /* send and receive */) = 0 [pid 27126] close(6) = 0 [pid 27126] close(7) = 0 [pid 27126] munmap(0x40276000, 4096) = 0 [pid 27126] open("/opt/interbase/interbase.msg", O_RDONLY) = 6 [pid 27126] read(6, "\1\0\0\4\10\377\1\0\0\0\0\0\3\0\r@", 16) = 16 [pid 27126] lseek(6, 130824, SEEK_SET) = 130824 [pid 27126] read(6, "\177\r\3\0`\363\1\0\377\377\377\377\370\376\1\0", 1024) = 16 [pid 27126] lseek(6, 127840, SEEK_SET) = 127840 [pid 27126] read(6, "\25\0\0\0\20\0\0\0*\0\0\0\350\3\0\0>\0\0\0\310\7\0\0[\0"..., 1024) = 1024 [pid 27126] lseek(6, 16, SEEK_SET) = 16 [pid 27126] read(6, "\0\0\0\0\0\0\0\0\1\0\0\0<\0\0\0arithmetic excep"..., 1024) = 1024 [pid 27126] --- SIGSEGV (Segmentation fault) --- [pid 27125] <... select resumed> ) = ?
