The code in ext/sysvsem/sysvsem.c seems to forget the allocation of the buf member of the semun struct when it calls to semctl(). I solved it adding: struct semid_ds semidbuf; to the declaration of local variables, and: un.buf = &semidbuf; before each call to semctl(); I configured PHP using: configure --enable-sysvshm --enable-sysvsem --with-curl=/usr/local/lib/libcurl.a --enable-pcntl This is the gdb stack trace: (gdb) where #0 0x402864e2 in __new_semctl (semid=770, semnum=0, cmd=2) at ../sysdeps/i386/i486/bits/string.h:315 #1 0x80be3a3 in zif_sem_remove (ht=1, return_value=0x81a13cc, this_ptr=0x0, return_value_used=0) at sysvsem.c:406 #2 0x80fe6cf in execute (op_array=0x81946b8) at ./zend_execute.c:1598 #3 0x80fe889 in execute (op_array=0x8186c14) at ./zend_execute.c:1638 #4 0x80e4289 in zend_execute_scripts (type=8, retval=0x0, file_count=3) at zend.c:810 #5 0x8062879 in php_execute_script (primary_file=0xbffffbd0) at main.c:1381 #6 0x8060850 in main (argc=5, argv=0xbffffc74) at cgi_main.c:778 #7 0x401c2b65 in __libc_start_main (main=0x8060054 <main>, argc=5, ubp_av=0xbffffc74, init=0x805ec7c <_init>, fini=0x81037bc <_fini>, rtld_fini=0x4000df24 <_dl_fini>, stack_end=0xbffffc6c) at ../sysdeps/generic/libc-start.c:111 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=17274&edit=1
