Wireshark crashes with an assertion failure on stray minus in filter
Summary
A typo in filter expression causes Wireshark to die with an assertion failure.
Steps to reproduce
Start/open a capture, click to the filter line, and write an invalid filter with a stray minus (hyphen), e.g. -tcp
and confirm with enter.
What is the current bug behavior?
Wireshark window freezes, a debug console window appears with an assertion failure error message.
What is the expected correct behavior?
The filter line stays red, indicating a wrong filter syntax, Wireshark definitely does not crash.
