Commit 6e6b74c0 introduced heap allocation in the form of QString::fromLatin1().utf16() into qEmergencyOut(), a function that's called in OOM situations and in cases where another exception is still in flight. Luckily, QString::fromLatin1().utf16() is just a funny way of copying an array of chars into an array of wchar_ts, so we do that manually now and use a static wchar_t buffer. While at it, also throw text elision into the mix. This commit also fixes the message passed to _CrtDbgReportW(). What should be displayed is the emergency_buf, not the format string. Also remove a similar allocation in qt_message_output(). Change-Id: I2c44a298fc0927bb992de4977a7e4a7b47b16b26 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
