          Issue ID: 24309
           Summary: Memory allocation failed on Azure pipeline
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: tim.dlang at t-online.de

The DMD tests on the Azure pipeline Windows_VisualD_LDC x64_Debug sometimes
fail with the following output:

../generated/windows/debug/64/unittest/test_runner.exe
core.internal.gc.impl.conservative.gc
   Creating library ..\generated\windows\release\64\unittest\test_runner.lib
and object ..\generated\windows\release\64\unittest\test_runner.exp
****** FAIL debug64 core.internal.gc.impl.conservative.gc
core.exception.OutOfMemoryError at src\core\lifetime.d(126): Memory allocation
failed

See for example here:

The same error happens for different PRs.

The unittests for module core.internal.gc.impl.conservative.gc seem to allocate
some bigger blocks for testing. Maybe that needs too much memory for this Azure
pipeline
