Hi,
I have a Qgis C++ plugin that adds a tool, I build my plugin using the
libraries of Qgis built from sources
<https://github.com/qgis/QGIS/tree/release-2_4> with Microsoft Visual
Studio as described here
<http://htmlpreview.github.io/?https://raw.github.com/qgis/QGIS/master/doc/I
NSTALL.html#toc14> .
My tool works fine with built Qgis but not with the installed Qgis 2.4.
When I activate my tool and then turn to another tool Qgis crash and write a
minimum dump file:
Dump File: qgis-20140915-111427-2760-1564-8fdd08a.dmp :
