[jira] Commented: (STDCXX-333) std::wfilebuf extracts more than 1 character from a 1 byte file

I tried to see if I could reproduce this problem on Cygwin. My version of
Cygwin doesn't have any locales so I tried to generate the en_US.UTF-8 locale
using the stdcxx localedef program. I got this error:
nls$ ../bin/localedef -c -f /home/mbrown/stdcxx/etc/nls/charmaps/UTF-8 -i
/home/mbrown/stdcxx/etc/nls/src/en_US en_US.UTF-8
call to system LC_ALL=C /usr/bin/locale -a /tmp/tdf4.0 2/dev/null: No such

Re: [jira] Commented: (STDCXX-333) std::wfilebuf extracts more than 1 character from a 1 byte file
I decided to look into this as an exercise in stdcxx debugging and
managed to figure out how to get around the error and generate the
en_US.UTF-8 locale. The change I made to make it work is in the
attached patch file. Let me know if this is the correct format
for patches or if you prefer something else.
Incidentally, the original test program for stdcxx-333 runs fine
on Cygwin with the en_US.UTF-8 locale so the error must be unique
to Linux.

Great! Thanks for the detective work!

I don't see the patch. Did you forget to attach it? (Sometimes the
attachments end up getting stripped by ezmlm even though they
shouldn't). If it's small, you might want to paste it directly into
your mail. Otherwise you might need to post it somewhere (e.g., on
your web page or in the issue itself).
Incidentally, the original test program for stdcxx-333 runs fine
on Cygwin with the en_US.UTF-8 locale so the error must be unique

Hmm. Very odd.

for patches or if you prefer something else.
I should have mentioned: when posting patches to the list please
start the subject line with the string [PATCH] to make it stand
out. It's also good to give the email a descriptive title, or
change it to one when following up on an unrelated topic (as in
this case :)
Read the section below for more on how to submit patches:
