--- Begin Message ---Package: libc6 Version: 2.3.6.ds1-13 Severity: normal Hello, I've found a behaviour difference in a C program, running correctly on Woody and don't in Sarge or Etch systems. The problem is in a "%n" converter sometimes not honoured as it should be, this only after an interrupted IPC message receive. I've built a testcase (see end of report) to let others reproduce it. Running the original faulty program with electric-fence library produced a core with a memory fault in sscanf(), but I didn't reproduce it with the testcase. I don't have a Sid computer to test it, but I'll try to build a chroot to do this. Here is the C program testcase.c : /* Test case for a possible glibc bug. Frédéric Boiteux <[EMAIL PROTECTED]> Scan two times the same string for each word with a sscanf(). Between them, wait for an IPC message using msgrcv() ; someone should interrupt this message receive using SIGALRM signal, like with command : killall -ALRM testcase The second scan fails, the '%n' converter isn't honoured !
