I have a stack trace generated by a stripped application which looks like this:
*** Check failure stack trace: *** @ 0x7f0e442d392d (unknown) @
Per the OP, the command in GDB to find the source line of code from an address is:
info line *0x10045740
Edit: Replaced "info symbol 0x10045740" which won't work under certain conditions (thanks @Thomasa88).
