Apparently, one of the recent binutils versions was not compatible with
gnu c++ programs anymore in the default configuration:
You needed to add '-Wl,--enable-runtime-pseudo-reloc-v2' to the g++
command line call to avoid the 0xc0000005 error.

In the most recent binutils version 2.20.51 (link to article 33216
above) this option has been enabled by default, and wxWidgets libraries
are built properly, the wxWidgets sampleMinimal executes just fine.

Best Regards,
