Description John Lindgren 2011-12-28 23:35:49 UTC 
testThreads.c: In function 'main':
testThreads.c:110:6: error: conversion to non-scalar type requested

Line 110 contains the cast (pthread_t) -1.  According to http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/sys_types.h.html, pthread_t is not required to be an arithmetic type.  In MinGW, pthread_t is a struct, so casting -1 to pthread_t is impossible.
Comment 1 Oliver Lange 2012-01-29 01:57:46 UTC 
Confirmed, with MinGW-pthreads, pthread_t is a struct.

From what i saw in the code, initialization is not required
in that test function, so just remove line #110 and you'll be fine.

Cheers..

GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org.
As part of that, we are mass-closing older open tickets in bugzilla.gnome.org
which have not seen updates for a longer time (resources are unfortunately
quite limited so not every ticket can get handled).

If you can still reproduce the situation described in this ticket in a recent
and supported software version, then please follow
  https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines
and create a new ticket at
  https://gitlab.gnome.org/GNOME/libxml2/-/issues/

Thank you for your understanding and your help.
