天津11选5开奖结果走势图 www.sxotsn.com.cn IDA 6.9 users on Mac OS X, who have suffered seemingly-apparent crashes while using IDA.
The Qt 5.4.1 libraries shipped with IDA 6.9 suffer from the following bug: https://bugreports.qt.io/browse/QTBUG-44708, which was apparently fixed in Qt 5.5.0.
If, when IDA crashes, you ever spotted a backtrace that looks like the following:
frame #0: 0x00000000 frame #1: 0x00d8a50d QtGui'QT::QTextEngine::shapeText(int) const + 1187 frame #2: 0x00d8b517 QtGui'QT::QTextEngine::shape(int) const + 1199 frame #3: 0x00d8c977 QtGui'QT::QTextEngine::width(int, int) const + 155 frame #4: 0x00d73571 QtGui'QT::QFontMetricsF::width(QT::QString const&) const + 163 frame #5: 0x00041184 idaq'___lldb_unnamed_function853$$idaq + 420 ...
then you’ve been a victim of this rather tiresome issue.
(note: frame #0 doesn’t quite matter; the 2nd line,
QT::QTextEngine::shapeText(int), is the important one)
We have applied the patch mentionned in the Qt bugreport & re-built the
libqcocoa.dylib Qt platform support.
You will have to:
- download & unzip the following archive: qcocoa.zip.
- verify the shasum of the libqcocoa.dylib file:
$ shasum libqcocoa.dylib afcf3603f593776c6f39f41f81e98843897cf0ed libqcocoa.dylib
- place the
libqcocoa.dylibbinary instead of the one in
Once that is done, those crashes shouldn’t happen anymore.
A big, big thank you to Willem Jan Hengeveld & Vladimir Putin, who have reported this!
