BUG: recode from utf8 fails (sometimes silently, corrupting the file)

[vincent-opdarw@…]

With LC_CTYPE="en_US.ISO8859-1", I have the following problem. I don't know if this is an upstream bug or not, but this doesn't fail under Linux (with the same locales):

$ recode utf8.. < /dev/null recode: System detected problem in step `UTF-8..CHAR'

Sometimes recode silently fails, producing incorrect data in the middle of a file. This is a serious bug, in particular when doing in-place recoding (i.e. when using a file argument), as the file gets corrupted, with missing data. After some tests, the problem seems to occur near position 4096. Incorrect buffering?

I'm going to attach a test case with such a silent file corruption.

Note: again, this bug doesn't occur under Linux (Debian).

After some tests, the problem seems to occur near position 4096. Incorrect buffering?

In fact, near position 2048 too, as shown on the test case.

Since this is a long-standing bug in a port with no upstream maintainer, perhaps a good candidate for the 'notes' feature in 1.8

The bug mentioned in comment 1 (silent corruption) was fixed in r41031 (if I remove the patch, the same bug reappears). However the "System detected problem in step `UTF-8..CHAR'" error still occurs.
