I've had a closer look at H5detect.c and from what I understand it relies heavily on C macros such as H5_HAVE_SIGSETJMP and H5_HAVE_SIGLONGJMP. And it happens that these macros aren't defined anywhere when using the autotools build system, while they are taken care of by the cmake alternative build system. Setting these macros by hand, H5detect doesn't fail on Bus error anymore. Thus I think part of the problem lies in the hdf5 build configuration. But still there is this glibc fix side effect to understand :/ Thanks, _g.
