|
|---|
| 23 | # Status: ORf
|
|---|
| 24 | #
|

| 25 | # Version: GNU Awk 3.0.2
|
|---|
| 26 | # Platforms: SunOS 4.1.1 (compiled with Sun cc)
|
|---|
| 27 | # IRIX 5.3 (compiled with SGI cc)
|
|---|
| 28 | # Problem: Deleting local array inside function causes fatal internal error (and
|
|---|
| 29 | # core dump. The error does not occur when the variable "x", unused in
|
|---|
| 30 | # the example, is removed or when the function is declared foo(x,p).
|
|---|
| 31 | # When the function is declared foo(p,x), adding a dummy line that uses
|
|---|
| 32 | # "x", e.g. "x=1" does not prevent the error. If "p" is not deleted,
|
|---|
| 33 | # there is no error. If "p[1]" is used to delete the lone element, there
|
|---|
| 34 | # is no error.
