Bug#367235: libvmime0: Crash in libvmime.so.0 when parsing a simple
Hi,
Have you been able to backtrace the segfault?
Running this code:
#include fstream
#include iostream
#include vmime/vmime.hpp
int main()
{
// Read data from f i l e
std::ifstream file;
file.open(hello.eml, std::ios::in | std::ios::binary);
vmime::utility::inputStreamAdapter is(file);
vmime::string data;
vmime::utility::outputStreamStringAdapter os(data);
vmime::utility::bufferedStreamCopy(is, os);
// Actually parse the message
vmime::refvmime::message msg = vmime::createvmime::message();
msg-parse(data);
vmime::refvmime::header hdr = msg-getHeader();
vmime::refvmime::body bdy = msg-getBody();
vmime::charset ch(vmime::charsets::UTF_8);
std::cout Subject:
hdr-Subject()-getValue().dynamicCastvmime::text()-getConvertedText(ch)
std::endl;
}
=== EOF ===
with hello.eml:
Date: Thu, Oct 13 2005 15:22:46 +0200
From: Vincent [EMAIL PROTECTED]
To: [EMAIL PROTECTED]
Subject: Hello from VMime!
A simple message to test VMime
=== EOF ===
works for me, without a segfault.
Does the above code work for you?
Regards,

The problem is probably the fact that From() does not return the same thing as a Subject(), which is only text. To extract From, you need to do something like this: std::cout From: hdr-From()-getValue().dynamicCastvmime::mailbox()-getName().getConvertedText(ch) hdr-From()-getValue().dynamicCastvmime::mailbox()-getEmail() std::endl; This should fix the segfault. If you take a look at the docs you'll see that To and Cc also require special treatment, as they contain an array of addresses.

Oh, I re-read the manual and indeed one has to use vmime::mailbox instead of vmime::text. You can close this Bug report as operator error. However... I did all the voodoo with dynamic cast to vmime::text and stuff, I expect to get a decent error message back at runtime. Otherwise, what is the purpose of all the song and dance and all the complicated type traits and templates? florin -- There was a typo, but on the wrong page. -- Vipin Kumar signature.asc Description: Digital signature
