It turns out to be reproducible for the session in question. The session loads when I disable the plugin, and crashes again on reload when I reenable the plugin. I still think it's freaky for a plugin to crash if not being used ;) Apparently it's related to the QMake project manager. Loading a qmake-based project into an already running session triggers the crash. Here's what happens: apr_pool_create_ex is called with NULL parent and allocator, leading to a nullptr dereference:

Not sure how this does not cause problems on Linux ...
It really *is* a freak crash. The code behaves as if the call to `apr_pool_initialize()` is never actually made in `svn::pool_create()`. I can assign the function's return to a variable and print that value (0, meaning success), but when I step through the function with a debugger I never actually get into the function. Same thing when I set a breakpoint in `apr_pool_initialize()`. All this works fine in kdesvn, suggesting something is getting seriously messed up somewhere in KDevelop. The only explanation I can find is that the compiler (clang 4.0.1) miscompiles the svncpp code in KDevelop (but not the comparable code in kdesvn, from which I copied certain things for testing). Compiler and/or linker don't generate the proper address for the apr_pool_initialize() function:
(lldb) l 40
40 if (!s_initialized)
41 {
42 if (apr_pool_initialize() == APR_SUCCESS) {
43 s_initialized = true;
