[Bug c/21813] New: dead lock for ftime and strftime in multhithread C program

[sitthisc at gmail dot com]

When I use a ftime function in a multhithread program, sometime it will stop and 
all thread that use this function will wait for a mutex lock. The information from 
GDB are following:-

Program terminated with signal 11, Segmentation fault.

Do anybody have any Idea for solve this problem? Thank you.

Note. I'm develope a program in solaris9 with GCC 3.3.2

Not a GCC bug, please report this to your libc provider (most likely glibc).
