linux - how to analyze the output of valgrind -

working on project using valgrind check code in process. got errors valgrind. not specified file name , line number. have searched , guess there may symbol table missed. run in gdb in can source code, symbol table there.

the next output of valgrind.

45 ==10858== 0x808855e: ??? (in /repo3/mydir/project1/sw/build/automod/lt_l.exe) 46 ==10858== address 0x6fdb0cc 24,244 bytes within block of size 24,640 free'd 47 ==10858== @ 0x6ceb51d: free (vg_replace_malloc.c:325) 4 48 ==10858== 0x8087079: ???

how find problem is? not specified file name , line no. caused makefile? (we utilize complex makefile). or output above, still can locate wrong code?

edit: can utilize gdb watch stack address above find wrong code?

thanks!
