Issue ID: 13646
Summary: static darray & pointer initializers always allocated
in shared(global) memory rather than in TLS
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: critical
Priority: P1
Component: DMD

import std.stdio, std.parallelism;
int[] buf = [1]; // int* buf = [1];
void main(){
writeln("tls var addr = ", &buf,", ptr = ", buf.ptr, ", value = ", buf[0],"
in main before");
auto task = task!fun();
task.executeInNewThread();
task.yieldForce();
writeln("tls var addr = ", &buf,", ptr = ", buf.ptr, ", value = ", buf[0],"
in main after");
}
void fun () {
writeln("tls var addr = ", &buf,", ptr = ", buf.ptr, ", value = ", buf[0],"
in child before");
buf[0] = 2;
writeln("tls var addr = ", &buf,", ptr = ", buf.ptr, ", value = ", buf[0],"
in child after");
}
produce output:
tls var addr = 1B21A0, ptr = 425080, value = 1 in main before
tls var addr = 1C93E8, ptr = 425080, value = 1 in child before
tls var addr = 1C93E8, ptr = 425080, value = 2 in child after
tls var addr = 1B21A0, ptr = 425080, value = 2 in main after
where 2 independent variables points to same global data
