Debugging windows

In Source\WTF\wtf\win\DbgHelperWin.cpp replace

#if !defined(NDEBUG) with #if 1

Then regular WTFReportBacktrace() works.

Enable core dumps on Linux

mkdir -p /tmp/coredumps
sudo bash -c 'echo "/tmp/coredumps/core-pid_%p.dump" > /proc/sys/kernel/core_pattern'
ulimit -c unlimited

Then to read stack traces run the following command:

Tools/jhbuild/jhbuild-wrapper --wpe run gdb --batch -ex "thread apply all bt" WebKitBuild/WPE/Release/bin/MiniBrowser /tmp/coredumps/core-pid_29652.dump &> trace.txt
