I tried to use gdb to debug the sorce I attached last email.
The instruction in my source which gives me the error is:
res = xsltApplyStylesheet(cur, doc, NULL);
Going inside with gdb I found the error here:
....

I tried to print the stack:

Could you help me to find the error?
Did you try to compile my source and executes it?
If in my original source I try to comment:
xmlMemSetup(xml2_free, xml2_alloc, xml2_realloc, xml2_strdup);
all is ok.
Best regards
Marco
