Hi all! I know this isn't a devel list, but thought someone here may have a clue I could use... I have a fairly big application that runs on Centos 7 (and 6 and 5). Sometimes (not often, but too often) when running under the ddd debugger, while sitting stopped at a breakpoint, it will suddenly spew an apparent segfault in, as it says at the top of the source file, "Assembly code template for system call stubs". The specific place always looks like this: T_PSUEDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS) ret_ERRVAL T_PSEUDO_END_ERRVAL (SYSCALL_SYMBOL) the red error marker points to SYSCALL_NAME. I have no idea why its doing this, it never does it when not running in the debugger, as far as I can tell. and why it would croak in the debugger while sitting (apparently) idle at a breakpoint is beyond me. anyone here got a clue? thanks in advance! -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only he who does the will of my Father who is in heaven." ------------------------------ Matthew 7:21 (niv) -----------------------------
