I am trying out the DJni library
(https://github.com/Monnoroch/DJni). For some reason
std.conv.to!string doesn't want to convert a char* to a
string.The lines below are taken from the log. I see that the
last frame is at gc_qalloc. I am not sure why it failed there.
Can anybody elaborate on what is going on here ? Thanks in
advance.
