No, i have not. After commenting the code to avoid the crash I switch to
another task. I will try it, hopefully it will tell us the source of the
issue.

Michel, were you able to try out my test below?

Works fine for me on both Linux and OSX.
I'm wondering if perhaps the problem is on the JPEG library end,
rather than with OIIO or std::string per se. Which version of
libjpeg are you using?
Can you try something for me? Alter the code as follows, and let's
see what happens:
else if (m->marker == JPEG_COM) {
if (! m_spec.find_attribute ("ImageDescription",
TypeDesc::STRING)) {
printf ("About to access m->data\n");
printf ("m->data is a string of length %d\n", strlen((const
char *)m->data));
std::string s = std::string ((const char *)m->data);
printf ("grabbed the string: '%s'\n", s.c_str());
m_spec.attribute ("ImageDescription", s);
printf ("completed\n");
}
Here's my suspicion: that somehow with your version of libjpeg, the
data in m->data is not a valid string (not NULL-terminated, for
example). If this is the case, then std::string is a red herring --
changing everything to char* would not help at all.

Hi everybody
In my other post i mentionned a crash with a specific file. We've
been able to find the source of the crash, and it seems to be the
comment field stored in metadata: oiio crashed in jpeginput, line 235:
else if (m->marker == JPEG_COM) {
if (! m_spec.find_attribute ("ImageDescription",
TypeDesc::STRING))
*_m_spec.attribute ("ImageDescription",
std::string ((const char
*)m->data));_*
}
We failed to understand why, being unable to see the content of the
variables. The file can be opened without any issue in XnView, Gimp,
ImageMagick. We have commented the line of code, and the file could
be loaded successfully.
I've attached the file, if someone using windows can try to load it,
i'd like to know if it works.
Thanks.
