          Issue ID: 24863
           Summary: DMD v2.109.0 on OpenBSD out of memory when attempting
                    to compile OneDrive for Linux
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Other
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: lfzamora81@gmail.com

Overview: Attempting to build onedrive for linux (https://github.com/abraunegg/onedrive) from source on OpenBSD, receiving 'out of memory' errors early in the build on a system with 8GB of memory and swap.

This is encountered as part of an earlier bug report to the project which can be seen here with many more details about the system and circumstances: https://github.com/abraunegg/onedrive/issues/2977

Steps to Reproduce: Details can be seen here: https://github.com/abraunegg/onedrive/issues/2977

But essentially starting from base OpenBSD 7.6 installation and following the instructions for onedrive on Linux project to install prerequisites which all pass OK during ./configure check.

Actual Results:

obsd$ gmake clean; gmake;
rm -f onedrive onedrive.o version
rm -rf autom4te.cache
rm -f config.log config.status
if [ -f .git/HEAD ] ; then \
        git describe --tags > version ; \
else \
        echo v2.5.3 > version ; \

gmake: *** [Makefile:106: onedrive] Error 1

Expected Results: Would expect 'onedrive' binary to be created and executable.

Additional Builds and Platforms: Just OpenBSD. Apparently the FreeBSD port builds without issue but there are non-trivial differences between the systems. As we are seeing demonstrated here.
