Bug description:
  Steps to reproduce:

  1. Build the package with LTO enabled
  2. From the source tree run: `plink --file toy --freq`
     (this needs the toy.map which is part of the src package)
  3. Check that it segfaults:

  23918 MB RAM detected; reserving 11959 MB for main workspace.
  .ped scan complete (for binary autoconversion).
  Performing single-pass .bed write (2 variants, 2 people).
  --file: plink-temporary.bed + plink-temporary.bim + plink-temporary.fam

  2 variants loaded from .bim file.
  2 people (2 males, 0 females) loaded from .fam.
  2 phenotype values loaded from .fam.
  Using 1 thread (no multithreaded calculations invoked).
  Before main variant filters, 2 founders and 0 nonfounders present.
  Calculating allele frequencies... done.
  Total genotyping rate is 0.75.
  Segmentation fault (core dumped)

  ------------------------------------------------------------

  4. Add optimize=-lto to DEB_BUILD_MAINT_OPTION
  5. Rebuild, test again, verify that it doesn't segfault.

  This is also causing autopkgtest failures.
