Hi, I looked in build.xml and found no ENABLE_SYMBOLS, but something others which sounds like that. So, I build X10 with following command: ant -DENABLE_GCC_SYMBOLS=true -DGCC_SYMBOLS=true -Ddebug=true -Davailable.procs=8 -DX10RT_SOCKETS=true -Doptimize=true squeakyclean dist
However, the buffer overflow arises instantly and no more output is done. A "valgrind --leak-check=full --show-leak-kinds=all X10Launcher Hello" shows: ==19578== Process terminating with default action of signal 6 (SIGABRT) ==19578== at 0x508C428: raise (raise.c:54) ==19578== by 0x508E029: abort (abort.c:89) ==19578== by 0x50CE7E9: __libc_message (libc_fatal.c:175) ==19578== by 0x516F56B: __fortify_fail (fortify_fail.c:37) ==19578== by 0x516D56F: __chk_fail (chk_fail.c:28) ==19578== by 0x516DAF3: __realpath_chk (realpath_chk.c:29) ==19578== by 0x402601: realpath (stdlib.h:45) ==19578== by 0x402601: Launcher::initialize(int, char**) (Launcher_Init.cc:184) ==19578== by 0x40295D: Launcher::Setup(int, char**) (Launcher_Init.cc:62) ==19578== by 0x401D10: main (main.cc:56) When I unset X10_HOSTFILE, "X10Launcher Hello" has no buffer overflow.
