Replace the "libqcocoa.dylib" to /Applications/IDA Pro 7.0/ida.app/Contents/PlugIns/platforms/libqcocoa.dylib

Solution:

ida7.0 using Qt5.6

crash stack:

Cause:

    TISInputSourceRef source = TISCopyCurrentKeyboardInputSource();
    CFArrayRef languages = (CFArrayRef) TISGetInputSourceProperty(source, kTISPropertyInputSourceLanguages);
    if (CFArrayGetCount(languages) > 0) {
        CFStringRef langRef = (CFStringRef)CFArrayGetValueAtIndex(languages, 0);
        QString name = QCFString::toQString(langRef);
        QLocale locale(name);
        if (m_locale != locale) {
            m_locale = locale;
            emitLocaleChanged();
        }
        CFRelease(langRef);
    }

langRef wild pointer

Fixed:

#import <Foundation/Foundation.h>

void QCocoaInputContext::updateLocale()
{
    /* https://bugreports.qt.io/browse/QTBUG-48772

    TISInputSourceRef source = TISCopyCurrentKeyboardInputSource();
    CFArrayRef languages = (CFArrayRef) TISGetInputSourceProperty(source, kTISPropertyInputSourceLanguages);
    if (CFArrayGetCount(languages) > 0) {
        CFStringRef langRef = (CFStringRef)CFArrayGetValueAtIndex(languages, 0);
        QString name = QCFString::toQString(langRef);
        QLocale locale(name);
        if (m_locale != locale) {
            m_locale = locale;
            emitLocaleChanged();
        }
        CFRelease(langRef);
    }
    
    */

    QString name = QString::fromNSString([[NSLocale currentLocale] objectForKey:NSLocaleIdentifier]);
    QLocale locale(name);
    if (m_locale != locale) {
        m_locale = locale;
        emitLocaleChanged();
    }
}
