Wireshark-bugs: [Wireshark-bugs] [Bug 12040] Print "Selected packets only" crashes application
Date: Mon, 29 Feb 2016 04:50:30 +0000
Comment # 7
on bug 12040
from Guy Harris
OK, I got a crash from the master branch; I had to select "Selected packets
only", and then select "Range", and then re-select "Selected packets only" to
get it.
Here's the stack trace:
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: EXC_I386_GPFLT

Bad pointer dereference, but no indication of whether it's a null pointer or
not.
That's probably the code that's drawing the print preview. It's deep in the
bowels of Qt, but maybe Wireshark itself set *something* up to cause the crash.
