Hi, I got an: *** glibc detected *** double free or corruption (!prev): 0x84c01000 *** using O_DIRECT with threads: this error appends if I run several threads wich are reading several files (opened with O_RDONLY|O_DIRECT) at the same time. The error doesn't appends if I open the files whithout O_DIRECT or if I place a pthread_join after each thread call. I'm sure that no double free is done. kernel version: 2.6.17 SMP PREEMPT glibc version: 2.3.6 filesystem: ext3 g++ used: g++ (GCC) 4.0.4 20060507 (prerelease) (Debian 4.0.3-3) Does somebody knows the reasons of the error? There are limitation to use O_DIRECT on a multithread application? Thanks in advance for any help. A.
