Bug-Description:
|
|
|
07a490 |
|
|
|
07a490 |
When bash is parsing a function definition that contains a here-document
|
|
|
07a490 |
delimited by end-of-file (or end-of-string), it leaves the closing delimiter
|
|
|
07a490 |
uninitialized. This can result in an invalid memory access when the parsed
|
|
|
07a490 |
function is later copied.
