I am not sure if you provide the whole backtrace. It seems this related
cc/input/top_controls_manager.cc.

libxwalkcore.so
Hi Xing,
Attaching the Breakpad-minidump file, in case you or someone you can suggest,
can figure out by looking at it,
how it can be parsed. Am assuming we need the symbol file in order to parse it.
Thats why was following this link
https://code.google.com/p/google-breakpad/source/browse/trunk/README.ANDROID

Thanks Xing,
Tried that , did spit out some info, but not the stack trace was looking for.
Again, the input file for the crash, was a Breakpad-minidump.
Not sure if the 'stack' cmd expected that file-format

After typing this command, pasting the crash stack, you may get a readable call
stack.

Subject: [Crosswalk-dev] Analyzing Breakpad microdump from crash in
libxwalkcore.so
Need some help on how to analyze the Breakpad dump, and convert into a readable
backtrace. Am trying to analyze a crash in libwalkcore.so, this crash itself
happen on cherry-picking a recent commit from chromium into crosswalk-14.
Crash gives me a Breakpad Microdump, that is all in hex stack pointers.
Tried to follow:
https://code.google.com/p/google-breakpad/source/browse/trunk/README.ANDROID
Specifically need help on part : III. Getting a stack trace on the host:
dump_syms $PROJECT_PATH/obj/local/$ABI/libfoo.so > libfoo.so.sym
Doe Not create the symbol file, throws an error :
ubuntu@ip-xxxx1:~$ ./dump_syms libxwalkcore.so > libxwalkcore.so.sym
libxwalkcore.so: file contains no debugging information (no ".stab" or
".debug_info" sections)
Also tried re-building adding (GYP_DEFINES) linux_dump_symbols=1, that too did
Not help.
