Comment:

 Interesting. Initially this change was added for openbsd specifically for
 ghc-6.5:
     changeset:f638fdfe1d9de1307355c8074fbff9c28342c0ef (2006)
 and later it was extended to cover osx:
     changeset:c2cd83e7d85c11e6a33e1cde263eb2312566d535 (2009)

 None of the reports hint at exact breakage.

 I guess both happened in -fvia-C mode where GHC's Evil Mangler had a
 chance to mangle stack canaries generated by fstack-protector.

 As ghc has no evil mangler anymore it could work. I'll prepare a patch.
