<pansysk75[m]> <gonidelis[m]> "hkaiser: any special flags..." <- In this example, if I change the algorithm to copy_if, I get runtime crashes
<pansysk75[m]> HPX build with default flags (tested on my windows machine and on rostam)
<pansysk75[m]> Seems to be specific to copy_if (and depends on the predicate function & the size of the result vector)
<gonidelis[m]> whaaat!
<pansysk75[m]> Just copy pasted the example, replaced hpx::experimental::for_loop with hpx::copy_if and added a predicate function
<pansysk75[m]> > <@gonidelis:matrix.org> hkaiser: any special flags needed for this to be able to run as a separate executable ? https://github.com/STEllAR-GROUP/hpx/blob/master/examples/quickstart/executor_with_thread_hooks.cpp
<pansysk75[m]> HPX build with default flags (tested on my windows machine and on rostam)
<pansysk75[m]> * In this example, if I change the algorithm to copy\_if, I get runtime crashes (Segmentation fault)
<pansysk75[m]> Seems to be specific to copy\_if (and depends on the predicate function & the size of the result vector)
<gonidelis[m]> even when you run for 1 core?
<pansysk75[m]> tested a few setups that crashed for >1 core and they dont crash on only 1 core
<pansysk75[m]> I might be doing something dumb tho, that's why I'm sharing it here
<pansysk75[m]> it's also non-deterministic (ie the exact same run might crash or it may not)
<pansysk75[m]> but its less likely to crash if i make the destination vector absurdly large
<gonidelis[m]> lol
