if one builds with Debug mode, and -O0 the build fails to links due to incorrect declaration & initialization of the static const class member. (Or move initialisation to individual .cpp files and keep only declaration in the header to make sure INVALID_INDEX can be used as both lvalue and rvalue).

A trivial patch can fix that:
--- sfcgal-1.3.0.orig/src/algorithm/connection.h
+++ sfcgal-1.3.0/src/algorithm/connection.h
@@ -44,7 +44,7 @@ public:

With that compilation succeeds, and test-suite also passes.

So it does indicate that enabling optimisations results in test-suite failure. Running that under a debuger, only shows that boost-unit-test hits a (double?) free upon tear-down / after exiting a testsuite.

Hi Dimitri,

Thanks for the patch, I'll include it in the Debian package and forward it upstream.

[Bas Couwenberg (sebastic)]

Even with the patch, the build still failed on i386, see: https://buildd.debian.org/status/fetch.php?pkg=sfcgal&arch=i386&ver=1.3.0-3&stamp=1470577726

Because the patch did not solve the build failure, I've closed the PR and opened an issue in the upstream tracker:

 https://github.com/Oslandia/SFCGAL/issues/132

[Dimitri John Ledkov (xnox)]

Correct the patch is to resolve a minor issue of not being able to build with -O0 and code not being correct to the nitty-gritty details of C++ standard. However the actual build-failure / test-suite crash is still there.

[Launchpad Janitor (janitor)]

This bug was fixed in the package sfcgal - 1.3.0-4

---------------
sfcgal (1.3.0-4) unstable; urgency=medium

  * Drop i386-ftbfs.patch, did not fix FTBFS on i386.
  * Skip tests on i386 architectures, causes FTBFS.

[Bas Couwenberg (sebastic)]

This issue should be reopened, because the bug is not fixed only worked around by skipping the tests on i386 architectures.

[Matthias Klose (doko)]

is this still seen in newer GCC releases, or in gcc-snapshot?
