--- Begin Message ---Package: libc6 Version: 2.3.2.ds1-10 Severity: normal Minimal test program to demonstrate problem: #include <stdio.h> #include <pthread.h> #define NTHREADS 30 void * thread(void * arg) { return NULL; } int main() { int i; pthread_t threadid; for (i=0; i<NTHREADS ; i++) { pthread_create(&threadid, NULL, &thread, NULL); pthread_join(threadid, NULL); } printf("Press RETURN: "); while (getchar() != '\n'); return(0); } When it prompts for keyboard input, notice how many "defunct" pids there are. Expected behaviour appears to happen under libc6 2.3.2-7, and when running under kernel 2.6.0test9 (the .deb in sid) with or without LD_ASSUME_KERNEL=2.4.0. It doesn't appear to matter whether I have libc6-i686 installed. (I'm not ruling out that it might be a bug in kernel 2.4.22) -- System Information: Debian Release: testing/unstable Architecture: i386 Kernel: Linux manlap 2.4.22-1-686 #6 Sat Oct 4 14:09:08 EST 2003 i686 Locale: LANG=en_GB, LC_CTYPE=en_GB Versions of packages libc6 depends on: ii libdb1-compat 2.1.3-7 The Berkeley database routines [gl -- no debconf information -- Paul Martin <[EMAIL PROTECTED]>
