Hello,
I just found a bug that affects a number of shells (pressumably the code there is from the same roots) in the parser. The following code; l='eval "$l"' eval "$l" Which sets off an infinite recursion on 'eval', should result in an infinite loop to be terminated by INT (doesnt' work) or at least end gracefully with an error "bash: out of memory". Instead the system has to kill the shell process because of SEGV fault. I'm not familiar with bash internals but it looks to me like some sort of heap overflow problem. I traced the system calls using 'strace' and it is extending the data area with brk() by 4k a time until finally, pressumaby it just doesn't check the error from brk() not finding anymroe memory. bestwishes laura -- View this message in context: http://www.nabble.com/bash-shell-parser-bug-t1295794.html#a3450069 Sent from the Gnu - Bash forum at Nabble.com. _______________________________________________ Bug-bash mailing list Bug-bash@gnu.org http://lists.gnu.org/mailman/listinfo/bug-bash
