Valgrind is right. I don't think you're likely to run into this on
non-pathological input, but it's a relatively simple fix.
Patch posted to dash@, arc
Package: dash
Version: 0.5.10.2-7
dash crashes when checking syntax of a script consisting of a very long
sequence of backticks:
$ printf %0d | tr 0 '`' | dash -n
Segmentation fault
Valgrind says it's a stack overflow:
Process terminating with default action of signal 11 (SIGSEGV)
3 matches
