Comment 1 Alan Modra 2019-02-19 22:51:52 UTC
This is a different testcase and different out of memory condition to pr24233.  Unlike pr24233 we report an out of memory error.  I think that is perfectly good behaviour for user input with silly sizes, in this case a NOTE section claiming to be 0xfffff7dd00 bytes in size.  While we could test for silly section sizes by comparing against file size, that doesn't work in all situations, eg. when section contents are encoded and the decoded size is much larger than the raw size.
