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...
I filed bug 906860.
OK, so my next question is how do I make gdb load this file?
