As I learn C, I decided to write a small dictionary program, for my linux box. Unfortunatly, I'm unable to proceed because of that weird bug which I can't debug (no source of crash). Any help is appreciated. strace: read(3, "\270) file box\n 3) \321\200\320\260\320\267\320\263. \320\277\321\200\320\265"..., 4096) = 4096 read(3, "mixture of vodka and beer\n", 4096) = 26 read(3, "", 4096) = 0 close(3) = 0 munmap(0xb7860000, 4096) = 0 write(4, "\320\275\320\276-\320\266\321\221\320\273\321\202\321\213\320\271@11618255\n\321\217\320\270\321"..., 3875) = 3875 close(4) = 0 munmap(0xb785f000, 4096) = 0 --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ gdb: Program received signal SIGSEGV, Segmentation fault. 0x80d15d70 in ??
