Bug 24309 – Memory allocation failed on Azure pipeline

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@src\core\lifetime.d(126): Memory allocation failed See for example here: https://dev.azure.com/dlanguage/dmd/_build/results?buildId=40283&view=logs&jobId=4eadb322-4cab-54fe-0034-466161775765 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
