Hmmm.. with -m64 it's reporting 80 MB used, 203 MB are really
marked as private bytes. Constant. If I use GC.minimize() it
goes up and down and sometimes consumes more than 203 MB. Best
is 100MB. But it doesn't leak endlessly like the 32bit variant.
Hmm, I try to rewrite example in C# and it just hangs in GC, when
str += "1" added 5 million times.
Then i fix this using StringBuilder, as documented. It works fine.
Next i searched flang forums for D's StringBuilder - found this
https://forum.dlang.org/post/l667ab$cfa$1...@digitalmars.com
auto strBuilder = appender!string;
foreach (i; 0 .. 50_000_00) {
strBuilder.put("a");
And it works too, for 32-bit also =)
Consuming about 100MB RAM.
