Ok. This is minimal app that crashes for me. If someone could try
this:
class App
{
this()
{
}
void crash( int val )
in
{
assert( val == 1 );
}
body
{
struct Foo
{
this( int k )
{
a = k;
}
int a;
}
Foo foo;
int[ Foo ] map;
map[ foo ] = 1; // Crash! bug?
}
}
int main( char[][] args )
{
App a = new App;
a.crash( 1 );
return 0;
}
And the previous case for the crash looks like this:
