Some perl distributions for windows includes pthreads-win32 implementation of pthreads. Strawberry Perl, I think. And for others I built pthreads-win32 myself and changed Makefile.PL a little bit. You can find fully compilable version for both windows and others OS here: https://github.com/olegwtf/sandbox/tree/master/xs-free-windows-problem	[reply]

I strongly suggest that you should compile your code with /E or equivalent to produce the post-preprocessor code and take a look at what is actually being call for malloc() and free(); because it almost certainly isn't the appropriate CRT routines. With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice.	[reply]

It says that free() is win32_free() and malloc() is win32_malloc().	[reply]

FWIW its `gcc -E Preprocess only; do not compile, assemble or link` But yes perl does redefine these things, http://perl5.git.perl.org/perl.git/blob/HEAD:/XSUB.h#l563 `563 # define malloc PerlMem_malloc 564 # define realloc PerlMem_realloc 565 # define free PerlMem_free` [download]	[reply] [d/l] [select]

Have you heard of perlclib? It advocates using Newx() and Safefree() instead of malloc/free	[reply]
Re^4: XS: free() outside of the main thread causes crash on Windows by OlegG (Monk) on Sep 25, 2014 at 07:45 UTC
Yes. I made following changes: `-free(msg); +Safefree(msg); -char thread_arg = malloc((strlen(msg)+1)sizeof(char)); +char *thread_arg; +Newx(thread_arg, strlen(msg)+1, char);` [download] But this didn't help. Still crashes	[reply] [d/l]
