[bug-gawk] Yet another: pointer being freed was not allocated

[Hermann Peifer]

Hi again,

Below another memory issue when using typed regexp. The error occurs 
both on Linux and Mac OS. The test code is completely invented and not 
related to any meaningful use of typed regexp, but I thought that the 
bug is worth sending to the list.

$ cat typedre.awk
BEGIN {
        a[1] = @/abc/
        b[1][2][3] = @/xyz/
        print typeof(a[1]), typeof(b[1][2][3])
        print a[1], b[1][2][3]

        a[1]++
        b[1][2][3] ""
        print typeof(a[1]), typeof(b[1][2][3])
        print a[1], b[1][2][3]
}
