Bug#913371: gnat-gps fails to build on 32-bit kernels, address space exhaustion.
Package: src:gnat-gps Followup-For: Bug #913371 gnat-gps/18 now fails to build on armhf, while 18-3 was succeeding on the same architecture. After investigation, the only successful builds of gnat-gps/18 on 32 bits architectures so far (armhf i386 powerpc) were registered with a 32 bits chroot on a 64 bits machine. I suggest the following architecture list, with only 64 bits architectures, but any better idea is welcome. amd64 arm64 mips64el ppc64el s390x alpha ia64 kfreebsd-amd64 ppc64 riscv64 sparc64

I think this is the best way forward. -- Ludovic Brenta.

Package: src:gnat-gps Followup-For: Bug #913371 Maybe we should restrict the architecture set for this binary package? I doubt that anyone is using a graphical IDE like gnat-gps on armel/mips/mipsel. On the other hand, building on all architectures improves the quality, so I would remove failing architectures instead of providing an explicit list. Any better idea?

Package: src:gnat-gps Followup-For: Bug #913371 The issue is reproducible on mipsel with MALLOC_ARENA_MAX = 1 DEB_BUILD_OPTIONS = noopt parallel=1 The package was building in experimental, the faulty version only differs by LDFLAGS += -Wl,--no-allow-shlib-undefined -Wl,--no-copy-dt-needed-entries The dependencies have not changed much either. Maybe the problem probably originates in compiler changes.

Virtual address space is per-process. So while disabling make-level parallelism reduces ram/swap consumption it has no impact on virtual address space exhaustion issues. Linux overcommits memory, so if you see a memory allocation error then it probably means you ran out of virtual address space. Exhaustion of actual ram/swap generally results in your process getting killed by the OOM killer. However, it fails with the same error on the same architectures. Reopening the bug. Sorry for the noise.
