Package: libxml2
Version: 2.14.5+dfsg-0.1
Severity: serious
Tags: patch upstream
Justification: Makes packages FTBFS
Forwarded: https://gitlab.gnome.org/GNOME/libxml2/-/merge_requests/336
Hello,
This simple program fails to build:
#include <stddef.h>
#include <libxml/xmlerror.h>
int main(void) {
initGenericErrorDefaultFunc(NULL);
}
/usr/include/libxml2/libxml/xmlerror.h:23:45: error: invalid use of void
expression
23 | xmlSetGenericErrorFunc(NULL, (h) ? *(h) : NULL)
The compatibility macro is indeed wrong in the NULL case. The attached
patch, submitted upstream, fixes this.
Samuel

Fix initGenericErrorDefaultFunc(NULL)
Calling initGenericErrorDefaultFunc(NULL) currently yields to
/usr/include/libxml2/libxml/xmlerror.h:23:45: error: invalid use of void
expression
23 | xmlSetGenericErrorFunc(NULL, (h) ? *(h) : NULL)
Indeed, even if h is nul, the compiler will try to give a type to *(h),
which can't work.
