<p>Hi,</p>
<p><br>
</p>
<p>I already tried valgrind, that doesn't give any hints. So far I haven't been able to reproduce this in R console, but could be just bad(?) luck as the whole crash happens so randomly. I am now running sourceCpp with rebuild = TRUE and subsequent function
calls on a loop, and it takes seemingly random amount of iterations until Rstudio crashes.</p>

<div>Hi Helske<br>
<br>
I've had this happen to me and if memory serves in my case it was due to a memory leak on the C++ side that didn't bother R too much but caused sourceCpp to crash. Maybe try valgrind?

<p>Hi,</p>
<p><br>
</p>
<p>In the bssm package (<a moz-do-not-send="true" href="https://github.com/helske/bssm" class="OWAAutoLink" id="LPlnk158659" previewremoved="true">https://github.com/helske/bssm</a>), I let the users define a state space model via own C++ functions which are
then exported as Xptr to R side, and passed back to C++ function for SMC/MCMC etc. Normally this works fine, but when user repeatedly modifies the model functions and re-exports them via repeated calls sourceCpp, sometimes whole Rstudio crashes. I haven't
been able to pinpoint the reason or minimal example. Have anyone else experienced similar issues or is it just me i.e. error in my own implementations?</p>
<p><br>
</p>
<p>Simplest case of this is the discretized SDE models, this is the function which user modifies:
<a moz-do-not-send="true" href="https://github.com/helske/bssm/blob/master/vignettes/sde_functions.cpp" class="OWAAutoLink" id="LPlnk922418" previewremoved="true">
https://github.com/helske/bssm/blob/master/vignettes/sde_functions.cpp, </a>and the relevant parts of the package codes are in src/function_pointers.h, src/sde_ssm.cpp and src/R_sde.cpp (I don't really expect anyone to read through all of these).</p>
<br>
<p>Best,</p>
<p><br>
</p>
