" - core dumped" : ""; ^~~~~~~~~ This leads to an eventual linker error due to the missing symbol: ld: 0711-317 ERROR: Undefined symbol: .WCOREDUMP ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information. According to the Linux man page, WCOREDUMP should be gated by an #ifdef WCOREDUMP(status) returns true if the child produced a core dump. This macro should only be employed if WIFSIGNALED returned true. This macro is not specified in POSIX.1-2001 and is not available on some UNIX implementations (e.g., AIX, SunOS). Only use this enclosed in #ifdef WCOREDUMP ... #endif ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77677&edit=1
