Thank you for the report @ercanduman !

@maxme this looks very similar to https://github.com/wordpress-mobile/WordPress-Android/issues/9997 to me, but I am not sure if they should be combined. Should they be combined? Also, should this be moved to a different repository such as https://github.com/wordpress-mobile/gutenberg-mobile/ ?

@designsimply this is the same class of bug (OOM), but the source of the problem is different from wordpress-mobile/WordPress-Android#9997 - this one should probably moved to https://github.com/wordpress-mobile/AztecEditor-Android

Looking at the stacktrace, this is certainly happening when a huge text is pasted to Aztec (we're doing some string operations and allocating memory after pasting text, at some point memory allocation fails and Aztec crashes).
