I just ran into this issue on a fresh install of Ardour 5.12 on my Intel machine, also Ubuntu 17.10. Selecting new project works, the audio driver dialog opens, then crashes when ALSA driver is started or sync to Jack is selected. Here's my console output:

 Not usually one to make “me too” bug reports, but as this is an absolute showstopper: Me too. Going to try to upload a backtrace.

Edit: It appeared to upload. Go me.
Edit 2: Ubuntu Studio 17.10, x86_64, AMD A6-7310, official Ardour 5.12 build.

 Me too and since I'm new here I'll start by sponsoring this issue.

I should add that unfortunately the problem persists when I downgrade to version 5.11.0.

So, looking at the stack trace the crash occurs in /usr/lib/ladspa/csladspa.so. Indeed, removing the csladspa package fixes it for me.

Has this bug been reported against the relevant csladspa package?

I had a quick look in the Debian bug tracker but could not find anything.

I'm happy to report it but do you know who maintains csladspa? Could you post a ink to the bug tracker if you have it please?

I'm not really familiar or involved with the debian project or ubuntu but a quick search turns up this:

It's already fixed upstream in csound-git since December 2017

PS. The issue was in /frontends/csladspa/csladspa.cpp:406 in init_descriptor(char*, int)
The std::string is on the stack and doesn't need to be free()ed:

-------------------8<---------------------
// global variable
static struct AuxData {
  ..
  std::string portnames[MAXPORTS];
  ..
} aux;


// function
init_descriptor(..) {
  ...
  string *ctlchn = aux[plugindex].portnames;
  ...
  delete[] ctlchn; //<< BUG
}

-------------------8<---------------------


Even though the commit message does not mention it, it was fixed as part of https://github.com/csound/csound/commit/7bad3e3801e219860d91b1845f42c87812fc1d89

Not an Ardour bug.

Having finally had a chance to look at this I agree that the primary bug here is in csladspa.so itself and I'd already removed the package before checking back here just now. However, I'd argue that crashing during startup without at least a diagnostic message is itself an Ardour bug, as non-programmers are never going to be able to work that out themselves.

@julianyon The issue happens directly in dlopen() when loading the plugin in LADSPA's discovery mechanism.
Short of using a separate application process to scan for plugins, there is nothing that we can do to protect against this.

LADSPA version 2 (LV2) addresses this -- one does not need to dlopen() to discover plugins, no crash at startup.

We'd rather not work-around issues that happen in plugins, but fix the plugins instead. Especially since we later load a plugin and expect it to reliably do realtime DSP... If a plugin want to wreak havoc it almost always can.
