The GUST group released a new version:
http://www.gust.org.pl/projects/e-foundry/lm-math/download
The main changes are the fix to the ascent/descent bug and the inversion of clockwise/anticlockwise contour integrals. IIRC, EFL/GTK ports were not affected by the ascent/descent bug and the contour integrals are not in the testsuite, so that will probably not really change anything. But just in case, I'm opening this issue...
