Hi Carlos,
I think there are at least two problems:
1) something is wrong with the unicode String comparison, but I have no clue
how it should work.
The tile contains > 10000 city POI, but mkgmap detects only 145 different names
with unicode. Method Mdr5Record.isSameByName(Collator collator, Mdr5Record
other) returns true for names which look very different to me.
2) We don't use the method Mdr5Record.isSameByName() when section Mdr25 is
written (Cities are sorted by country and then by the mdr5 city record number).
Instead normal java String.equals() is used and thus the list contains the
expected > 10000 entries. This list requires a two-byte value in the index.
The crash happens because we try to write the position in the mdr25 list with
only one byte cause of this code in Mdr29.java:
int size25 = sizes.getSize(5); // NB appears to be size of 5
(cities), not 25 (cities with country).
The comment already shows that this is probably only correct when boths lists
have the same number of entries.
I hope Steve or Ticker have an idea what's wrong.
Gerd

Hi Carlos,
I can reproduce the crash. Not sure where to fix this yet...

Betreff: [mkgmap-dev] java.lang.AssertionError while building index from
unicode tiles
Hi all
I'm getting error below while building index from this tile:
https://files.mkgmap.org.uk/download/523/31177029.o5m. Minimum mkgmap
options triggering the error are: java -jar mkgmap-trunk.jar
--bounds=bounds.zip --index --unicode 31177029.o5m
Another tile from the same splitter run also fails but all other 65 of
67 build fine. With --code-page=936 they all build fine.
Command output:
Exception in thread "main" java.lang.AssertionError: 10586
