--- Comment #4 from Carlos Alberto Lopez Perez <clopez at igalia.com> ---
I have attached 3 backtraces generated on a GTK debug build at r198875.

All are crashing in the same place:

#0  strlen () at ../sysdeps/x86_64/strlen.S:106
#1  0x00007fb6e1bf3914 in WTF::StringImpl::create (string=0x3 <error: Cannot access memory at address 0x3>) at ../../Source/WTF/wtf/text/StringImpl.cpp:288
#2  0x00007fb6e1c064c3 in WTF::String::String (this=0x7fffe4fb24e8, characters=0x3 <error: Cannot access memory at address 0x3>) at ../../Source/WTF/wtf/text/WTFString.cpp:82
#3  0x00007fb6e6de7d36 in Inspector::Protocol::getEnumConstantValue (code=129) at DerivedSources/WebKit2/AutomationProtocolObjects.cpp:123


It seems WTF::String::String is trying to access an invalid memory address after Inspector::Protocol::getEnumConstantValue
