Debugging ASP.Net applications causes the debugger to segfault. Depending upon
|
|
the complexity of the application, you may be able to get the app up and
|
|
running in debug mode (the MVC project created by monodevelop, for example, can
|
|
often be debugged happily provided that you have no breakpoints), but if you
|
|
can get up and running the debugger is unstable. For example, setting a
|
|
breakpoint inside RegisterRoutes() in Global.Asax.cs in the MVC project created
|
|
by monodevelop doesn't always cause the debugger to crash, but subsequently
|
|
hovering on the call to RegisterRoutes() in ApplicationStart() will cause the
|
|
debugger to fail. More consistently, setting a breakpoint in HomeController.cs
|
|
seems to always cause the debugger to crash.
|
|
|
|
Reproducible: Always
|
|
|
|
Steps to Reproduce:
|
|
1) Ensure that the contents of /proc/sys/kernel/yama/ptrace_scope are "0" not
|
|
"1" to prevent a ptrace: operation not permitted error
|
|
2) Create a new ASP.Net MVC Project
|
|
3) Set breakpoint on line 16 of the generated ./Controllers/HomeController.cs
|
|
file
|
|
4) Launch the debugger in monodevelop.
|
|
Actual Results:
|
|
The debugger segfaults
|
|
|
|
|
|
|
|
Expected Results:
|
|
Debugger breaks on line 16 of HomeController.cs
|
|
|
|
I've seen this in both mono 2.6 (from the ubuntu repos) and 2.8 (built from
|
|
source) using Monodevelop 2.4, again both from repos and built from source.
|
|
|
|
I'm running Kubuntu 10.10.
