    <p>I'm trying to create a program that manages simple threads. This is the main program:</p> <pre><code>int main(int argc, char **argv) { printf("test2:\n--------------\n"); clock_t stop1; uthread_init(100); printf ("***%d***\n",uthread_get_tid()); if(uthread_spawn(f1)==-1) printf("FAIL: uthread_spawn failure\n"); stop1 = clock () + 0.05 * CLOCKS_PER_SEC; int i; printf ("StartLoop of thread: ***%d***\n",uthread_get_tid()); while(clock ()&lt;stop1) { for(i=0;i&lt;10000000;i++) {} } printf ("FinishLoop of thread: ***%d***\n",uthread_get_tid()); uthread_terminate(0); return 0; } </code></pre> <p>The code is creating new Thread, which then creates a new thread, which then creats a new Thread. While creating the 3 third, I get the error. The program stucks here (In the creating thread function):</p> <pre><code>int uthread_spawn(void (*f)(void)) { DBG(("Spawning !")) //checking if number of threads is bigger then max if (getThreadCount() &gt; MAX_THREAD_NUM){ errmsgLibrary(MAX_THREADS_LIM); return FAIL; } // TODO - Check if needed to block/unblock here if (blockTimerSignal(BLOCK) == SUCCESS){ DBG(("Block signal success")) DBG(("ntid value: %d",nTid)) pThread t = new Thread(f,nTid++); DBG(("new thread created")) t-&gt;setState(Thread::READY); ready.push_back(t); DBG(("Added new Thread - %d",(nTid-1))) DBG(("Number of threads in ready list is - %d",(ready.size()))) blockTimerSignal(UNBLOCK); return (nTid-1); } DBG(("Block signal not success")) return FAIL; } </code></pre> <p>While trying to create new Thread().</p> <p>The error I get is:</p> <pre><code>test02-new: malloc.c:5161: malloc_consolidate: Assertion `p-&gt;fd_nextsize-&gt;bk_nextsize == p' failed. Abort </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
