# Subject: GNU awk 3.0.2 bug: fatal error deleting local array inside function
# Status: ORf
# 
# Version: GNU Awk 3.0.2
# Platforms: SunOS 4.1.1 (compiled with Sun cc)
#            IRIX 5.3 (compiled with SGI cc)
# Problem: Deleting local array inside function causes fatal internal error (and
# 	core dump. The error does not occur when the variable "x", unused in
# 	the example, is removed or when the function is declared foo(x,p).
# 	When the function is declared foo(p,x), adding a dummy line that uses
# 	"x", e.g. "x=1" does not prevent the error. If "p" is not deleted,
# 	there is no error. If "p[1]" is used to delete the lone element, there
# 	is no error.
# 
# ==== The program x.gawk ====

function foo(p,x) {
	p[1]="bar"
	delete p
	return 0
}

BEGIN {
	foo()
}

# ==== The output for "gawk -f x.gawk" (SunOS) ====
# 
# gawk: x.gawk:4: fatal error: internal error
