Responsible Changed From-To: freebsd-bugs->ru I'll look into it. It's unfortunately not a BSD awk, but a one-true-awk, externally maintained. We have sent a pool of local fixes upstream, but didn't hear back from Brian Kernighan yet. ru 2006-10-25 21:23:21 UTC

Our awk (bsd awk) seems to coredump when a function locally assigns a string to a parameter that was initialized by the function call to a non-zero numeric value. Fix: unknown How-To-Repeat: This is the smallest snippet that reproduces the problem described above: # awk 'function f(x) {x=""} BEGIN {f(1)}' awk in free(): error: junk pointer, too low to make sense Abort trap (core dumped)
