artemp/trac2github — Issue #566: segfault when on osx when compiled with clang++ as exceptions are somehow not handled properly

Lastest trunk on osx 10.6, with boost trunk compiled with g++, and mapnik compiled with clang++ (trunk) segfaults during the python tests.

I can isolate it down to the glyph_symbolizer test:

$ nik2img.py tests/data/good_maps/glyph_symbolizer.xml crash.png
Segmentation fault

with mapnik compiled with g++ i see the error is actually a runtime error that is not being caught by boost python:

{{{
======================================================================
ERROR: python_tests.glyph_symbolizer_test.test_load_save_load_map
----------------------------------------------------------------------
Traceback (most recent call last):
File "/Library/Python/2.6/site-packages/nose-0.11.1-py2.6.egg/nose/case.py", line 183, in runTest

File "/Users/dane/projects/mapnik-dev/trunk2/tests/python_tests/glyph_symbolizer_test.py", line 45, in test_load_save_load_map

RuntimeError: Failed to parse attribute 'halo_fill'. Expected type color but got 'rgba(0%,0%,0%,4%)' in GlyphSymbolizer in style 'arrows' in map '../data/good_maps/glyph_symbolizer.xml')
}}}

So, basically mapnik now crashes rather than throwing a python exception... this is just the first error it hit during the tests:
