Is there any way to catch a segfault caused by Qt (for example, to log it to
a file, etc)? I've tried installing a handler for the SIGSEGV signal, but it
doesn't seem to work when a segfault occurs within PyQt. Example:
#####################
# install a signal handler
import signal
def handler(signum, frame):
print "Signal handler for signal", signum
signal.signal(signal.SIGSEGV, handler)
from PyQt4.QtCore import *
from PyQt4.QtGui import *
app = QApplication([])
model = QStandardItemModel(1,1)
model.setItem(0,0,QStandardItem("foo"))
proxyModel = QSortFilterProxyModel()
proxyModel.setSourceModel(model)
# cause a Segmentation fault to happen
print "causing segfault"
index = proxyModel.index(0,0)
print index.internalPointer()
app.exec_()
########################
when I run this, the program just hangs forever, and I never see the print
statement in my handler.
