Hello,
Thanks for all the advice. Now it gets a lot further:
I built webkitfltk with -fno-pie, and the test program loaded, showed 
a window, and crashed somewhere in JavaScriptCore.

I tried running Source/JavaScriptCore/jsc, and it shows a problem that
was previously reported:

$ Source/JavaScriptCore/jsc
Error compiling builtin: 
ASSERTION FAILED: result
parser/Parser.h(970) : WTF::PassRefPtr<T> JSC::parse(JSC::VM*, const JSC::SourceCode&, JSC::FunctionParameters*, const JSC::Identifier&, JSC::JSParserStrictness, JSC::JSParserMode, JSC::ParserError&, JSC::JSTextPosition*) [with ParsedNode = JSC::ProgramNode]
Segmentation fault (core dumped)


Upstream has set thread stack size to 1 megabyte regardless of libc, 
figuring that 8 megabytes is too much.
I'm building with -DUSE_SYSTEM_MALLOC=1.
Looking through the old thread on Webkit javascript crashing, I found an 
excerpt of a diff, but could not figure out where it's supposed to apply
(grep -r didn't find anything pertinent that I could see).

Thanks,
Isaac Dunham
