Does Linux have a debugging story? On Windows x86 I can happily let the
application run and when it crashes I click Debug and WinDbg is launched
for me, and I can inspect the crash state and possibly fix things up and
resume the application. Or I can launch the application from WinDbg and
ignore all first chance exceptions so that only real crashes break into
the debugger.
On Linux I used to launch the application under gdb, however recently
some JS changes made this unhelpful as gdb catches the various SIGSEGV
and/or SIGBUS signals that the JS engine deliberately triggers. If I
ignore those signals then if I run into a real crash then the
application will just quit, which defeats the object of running a
debugger. I can set a breakpoint on AsmJSFaultHandler+49 but it's
presumably too late to get back to the execution state at the point of
the signal...
