Fixed in 1.1.3 - see issue1251.

I found the problem.  It is a plain stupid double free bug of an internal fixed
size buffer.  Will be fixed soon.

For the problem with the corrupted attachments, please see issue1251.

Tested with gpgol 1.1.2:
Open an openpgp signed+encrypted message with attachments. Outlook 2007 crashes
after double clicking the txt attachment. Gpgol log file attached.

Tested with gpg4win-2.1.0-svn1497 (= gpgol 1.1.2) + kleo 2.1.0-svn1156672:

Same problem as reported in msg3247.

I have completed Christoph's tests with these 2 on WinXP (see text file
enclosed for details):

	1 - if the original mail was PGP encrypted, forwarding it would
	break attachments even though the mail is "clear" forwarded =
	neither signed nor encrypted

	2 - broken attachement depends on orignal file format: a file
	zipped under linux would not be broken whereas the same file zipped
	with IZarc under WinXP would (Christoph reports that an
	7-Zip archive would break as well)

Do not hesitate to ask for further tests on Win7 or WinXP if you need.

There is also an issue1251 (GPGOL creates broken attachments in Outlook 2007)
about creating encrypted messages. I believe we have two seperate issues
here, though of course they might be caused by the same defect.

However issue1110 even crashes on correct attachements created by Kmail
and issue1251 leads to attachments that even mutt cannot decrypt.

Tested with different mailer of sender:
An OpenPGP encrypted (or encrypted/signed) email sent by OL2007/GpgOL1.1.1 and
Kontact e35 (GNU/Linux).
Same problem for both emails: OL2007 crashes after opening an attachment.

It's a very critical issue for OL2007.
msg3630 (view) Author: emanuel Date: 2010-04-15.11:26:32
Still the same problem with gpg4win 2.0.2 (aka GpgOL 1.1.1).
msg3426 (view) Author: bernhard Date: 2009-12-01.13:53:34
Werner or Emanuel, any updates on this issues?
Still reproducable witn 2.0.1 (aka GpgOL 1.0.1)?
msg3347 (view) Author: emanuel Date: 2009-09-17.09:25:29
Still the same problem with Gpg4win 2.0.1-rc1.
msg3247 (view) Author: emanuel Date: 2009-08-21.10:32:10
Decrypt an OpenPGP encrypted email with Outlook2007 + GpgOL 1.0.0.
Open any attachment of this email.
-> Outlook2007 crashes!
(GpgOL log doesn't contains a reference to this problem.)

Tested with Gpg4win 2.0.0 + Vista + Outlook2007.

[There is _no_ problem with Outlook2003 (+ GpgOL 1.0.0 + WinXP).]
