Hi,
Vim crashes on Windows when opening very long filename if enc is utf-8.
How to reproduce:
1. Create a file with very long name.
echo
foo>aaああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああああ.txt
Note that this filename is shorter than MAX_PATH (260) bytes in the current
codepage, but longer than MAX_PATH bytes in utf-8.
2. Open the file with a wildcard. 'enc' should be utf-8.
vim -u NONE --cmd "set enc=utf-8" aa*.txt
This is caused by that allocated buffer is not enough.
Following patch fixes this:
--- a/src/misc1.c
+++ b/src/misc1.c
@@ -9941,7 +9941,7 @@ dos_expandpath(
}
/* make room for file name */
- buf = alloc((int)STRLEN(path) + BASENAMELEN + 5);
+ buf = alloc(MAXPATHL);
if (buf == NULL)
return 0;
