[Pkg-geany-team] Bug#744196: geany-plugin-debugger: geany crashes when debugging reaches pthread_create

[Stefan Arnold]

Package: geany-plugin-debugger
Version: 1.23+dfsg-3
Severity: normal

Using the debugger tool, geany crashes when stepping over or into
pthread_create. Try following code:

-------------------------
#include <stdio.h>
#include <pthread.h>
#include <unistd.h>

static void *handler(void *data)
        {
        sleep(5);

        return NULL;
        }

int main(int argc, char **argv)
        {
        pthread_t thread_id;

        if(pthread_create(&thread_id, NULL, handler, NULL) != 0)
                {
                printf("\"pthread_create\" failed\n");
                return -1;
                }
        pthread_join(thread_id, NULL);

        return 0;
        }
-------------------------------

strace:
.........
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=5,
events=POLLIN|POLLPRI}, {fd=18, events=POLLIN}, {fd=12, events=POLLIN}, {fd=8,
events=POLLIN}], 6, 46) = 1 ([{fd=18, revents=POLLIN}])
clock_gettime(CLOCK_MONOTONIC, {699381, 983837424}) = 0
write(4, "\1\0\0\0\0\0\0\0", 8)         = 8
read(18, "=thread-created,id=\"2\",group-id="..., 1024) = 103
