getting segmentation fault in the program (no replies)

I am getting a segmentation fault sometimes in my application(It comes very rarerly, like once in 300 runs of program. Since it doesnt come always so I cant gdb it).

*** Aborted at 1362124211 (unix time) try "date -d @1362124211" if you are using GNU date ***
PC: @ 0x8ae07b my_stat
*** SIGSEGV (@0x0) received by PID 7495 (TID 0x7f0bbfafe700) from PID 0; stack trace: ***

@ 0x8ad28c get_charset_by_csname
@ 0x8b990d mysql_init_character_set

I am not sure why I am getting this. Any ideas what it means or if I can use this information to reproduce this.
