[Dart] [Coverage] hidden symbol `__bb_init_func' dart

[Mathieu Malaterre]

Just for reference, I gave up on using gcc-3.3.5 and switch to 3.4.4:

$ gcc-3.4 --version
gcc-3.4 (GCC) 3.4.4 20050314 (prerelease) (Debian 3.4.3-13sarge1)

Conclusion is works out of the box !

Steps:
export CC=gcc-3.4
export CXX=g++-3.4
export CXXFLAGS="-g -O0 -fprofile-arcs -ftest-coverage"
export CFLAGS="-g -O0 -fprofile-arcs -ftest-coverage"
export LDFLAGS="-fprofile-arcs -ftest-coverage"

then you can link your executable to shared libs.

Instructions are now in the Wiki:

Ps: I wish I was using good ol' bug free closed source software ;)
