#10 std::bad_alloc error in bbpager

[Anonymous]

Trying to load bbpager on blackbox startup and put in
the slit.

xxx@pirate$ bbpager -w
xxx@pirate$ terminate called after throwing an instance
of 'std::bad_alloc'
what(): St9bad_alloc

+ Abort trap (core dumped) bbpager -w
xxx@pirate$

Above is the error received. Can call bbpager from
within blackbox, but cannot put in slit.

You have this problem when you do bbpager -w after
blackbox is started ?

Can you please attach the core dump.

Yes, I have the problem after blackbox is started.

Cannot find an editor that can read the dump, otherwise I
would attach it.

I too get this once in a while. I always run bbapger -w and after a couple of hours it will abort. Here is the backtrace.

(gdb) r -w

Running it inside valgrind immediately gives this ...

So, whats happening is, that PagerWindow::buildWindow is called without the following fields being initialized: desktop_nr, window_x, window_y. At least, that's how I read it.
