Dear Eli,

FYI, I have rebuilt with replacing c:/ pathes by /c/ pathes, and the
make went to the end --- however, like for you it crashes when launched
interactively, here is a log.

-----------------------------------------------------------------------

Just to double check I am reverting to c:/ and rebuild again. In the
unknown exception I had seen something related to TimeZone requesting
from the OS, I would like to be sure that the crash is not time
dependent by testing again.

I'll let you know next time if the patch solves it for me too.

   Vincent.
