[Gpg4win-users-en] pinentry.exe crashes in GPG4Win-Light on Windows 7 Prof. with Russian locale

Hi and thanks for your replies!

(sorry for sending it wrongly for the first time, I confused "reply"
button with "reply to all")

Well, I should have thought of that earlier. Installed Full version with
GPA checked, that worked normally!

I failed to make pinentry.exe crash manually, no matted what I asked it
to display. I also tried to write a program to replace standard
pinentry, read STDIN and ask me interactively what to reply to it, but
couldn't make gpg-agent run a perl script like a normal executable with
stdin and stderr connected where they belong.

But that probably doesn't matter, see below.

If nothing else helps, I'll join Gpg4win-devel, try to get gdb working
on my Windows machine, get the version with debug symbols and acquire a
backtrace.

Or are we already too technical? :)

"pinentry-gtk2 0.8.4-beta8", just like pinentry-gtk-2.exe. In fact,
pinentry.exe is the same as pinentry-gtk-2.exe (checked with 'fc'), but
saying "pinentry-program ...pinentry.exe" in gpg-agent.conf does not
make it work.

Furthermore, pinentry-w32.exe exits immideatly on startup if run from
cmd and does not respond to --version, but if I rename it to
pinentry.exe without creating gpg-agent.conf, it does work properly
(being called from gpg-agent, not manually).

P.S. Stopped to recheck what I wrote about pinentry-gtk-2.exe and
realised that "pinentry-program ...pinentry-gtk-2.exe" solution stopped
working too.

Rewrote my logging pinentry in C (source attached), but if run from
gpg-agent, it just truncates the log and hangs despite looking
identically to pinentry-gtk-2.exe when run from cmd.exe.

Best regards,
Ivan.
