It is reproducable with just one thread too. This should be the simpler case:
#include
#include
#include
void *do_thread(void *) {
int niterations = 200;
int i;
#pragma omp parallel for
for (i = 0; i < niterations; i++)
{
printf (
Hi, I think I have figured it out:
The issue may be that internally openmp may be allocating thread
identifiers that may already be used by pthread so pthread_join
somehow ends up waiting for the parent thread to finish, deadlocking
itself.
Try this:
#include
#include
#include
void *do_threa
Indeed. I do not have much experience with thread programmng unfortunately. :/
In any case trying to debug this from within blender is quite hard
because I can't get a stacktrace. A disassembly shows that the problem
occurs within pthread_create_wrapper. Here is a small disassembly
around the cras

This won't be very useful since I do want to switch to MSVC++. Thanks for
the tip though.

This test program is invalid. Your application tries to create an
thread and afterwards immediately terminates (by returning from main).
By add the line 'pthread_join (id, NULL);' after creation of the
thread, you will see the message "I am a thread!" as expected.

Well, Qt Creator should support also mingw-w64 for 64-bit (and
32-bit). On their support-page I didn't saw that.

The correct form is probably:
IsEqualGUID(&FORMAT_WaveFormatEx, &FORMAT_WaveFormatEx);
Your form would be valid in C++, but not i
Hello,
I was wondering whether it is possible to use static libraries built with
mingw (e.g. libz) in a Visual C++ and link against them.
To explain the motivation behind this: in my current setup, I'm using mingw
to build both my application and my toolchain (which comprises of a number
of libra
I don't know if this is a bug, or even the right forum, but this line:
IsEqualGUID(FORMAT_WaveFormatEx, FORMAT_WaveFormatEx);
using cross compiled mingw-w64, in a ".c" file, seems to yield this:
libavdevice/dshow.c:607:3: error: incompatible type for argument 1 of ‘memcmp’
In file included from
Just as a note, removing the 'private' openmp directive also crashes.

Hi, I am looking into openmp-related crashes that we've had into
blender. I see that the issue is known (
http://www.mail-archive.com/mingw-w64-public@lists.sourceforge.net/msg03982.html
) and that people from this mailing list have requested test files to
debug so I am sending a small program that

This is possible, as I saw this recently
