According to run.dlang.io, issue introduced in DMD 2.102.1
Code:
---------------------------------------
void main()
{
asm
{
NOP;
}
}
---------------------------------------
Result (DUB with DMD 2.102.2 Linux):
Error /home/ndf/dlang/dmd-2.102.2/linux/bin64/dmd failed with exit code -11.

The compiler seemingly fails with this message:

----------------------------------------
Digger blames:

digger: 5b4d3c47e26c1e32cd5425f31ac390f992ac34f9 is the first bad commit
