Segmentation fault in FreeBSD 9.0 flockfile ()

[Unga]

Hi all

I'm getting a  Segmentation fault in FreeBSD 9.0 as follows for myprog.c:


Reading symbols from /libexec/ld-elf.so.1...done.
Loaded symbols for /libexec/ld-elf.so.1
#0  0x28ebb062 in flockfile () from /lib/libc.so.7

I don't use flockfile () directly in my program.


I use -lpthread.

Same program runs without any issue on FreeBSD 8.1.


Any idea what's going on?

Best regards
