http://www.mbayer.de/html2text/issues.shtml The problem is in the usage of get_attribute, which is a variable argument function. The function checks for a NULL (char *) argument to terminate processing. Callers used 0 to represent the end of the list, which fails on architectures where int is not the same length as (char *). Callers should use NULL when they mean NULL. C++ blurs the difference between 0 and NULL much more than C. In a variable argument function call, there is still a difference. Larry Doolittle very kindly wrote a a patch that fixes this. It can be found in the program's downloads directory.
