Description Sergei Dolmatov 2003-09-28 14:48:59 MSD

buildreq вешается после запуска программы проверки наличия работоспособного
pthreads. Текст программы из ./configure:

$ cat conftest.c
#line 4164 "configure"
#include "confdefs.h"

#include <unistd.h>
#include <pthread.h>
int pid;
void
testpid(void *ignore) {
	int mypid = getpid();
	(void)ignore;
	/* All threads should have the same PID! */
	if(mypid != pid)
		exit(1);
	else
		exit(0);
}
int
main(void) {
	pthread_t child;
	pid = getpid();
	pthread_create(&child, NULL, testpid, NULL);
	pthread_join(child, NULL);
	return 1;
}

При запуске этой откомпилированной программы вручную и при обычном ./configure
все проходит нормально, возвращает 1.

Ядро: 2.4.20-alt10-up
rpm-utils-0.7.3-alt1
strace-4.4.99-alt1

Steps to Reproduce:
1. Взять и установить ipcad-2.9-alt1.src.rpm
2. Запустить buildreq ipcad.spec

Comment 2 Dmitry V. Levin 2003-09-28 16:47:31 MSD

This simple pthread test fails. 
$ gcc -Wall -Werror stracetest.c -lpthread -o stracetest 
$ strace -fF ./stracetest 
 
Tested on: 
glibc-2.2.6-alt0.10 + kernel-2.2.25-alt1-smp-secure + strace-4.4-alt6 
glibc-2.2.6-alt0.10 + 2.4.20-alt10-up + strace-4.4.99-alt1

Comment 7 Dmitry V. Levin 2003-10-06 11:59:40 MSD

Между прочим, хоть проблема и в strace'е, тест в ipcad-2.9-alt1.src.rpm всё равно 
кривой.

Comment 8 Dmitry V. Levin 2003-12-15 02:55:25 MSK

Fixed in strace-4.5.1-alt1
