Would there be in simple reason, why the binary works in RedHat, but not in Debian ?
From the strace of running my program: oldselect(5, [3 4], [], NULL, {0, 0}) = -1 EFAULT (Bad address) gettimeofday({848498578, 216602}, NULL) = 0 oldselect(5, [3 4], [], NULL, {0, 0}) = -1 EFAULT (Bad address) gettimeofday({848498578, 222522}, NULL) = 0 mmap(0, 258048, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x400cd000 brk(0x813b000) = 0x813b000 brk(0x8119000) = 0x8119000 close(3) = 0 close(7) = 0 --- SIGCHLD (Child exited) --- wait4(-1, [WIFEXITED(s) && WEXITSTATUS(s) == 0], WNOHANG, NULL) = 3958 wait4(-1, 0xbffff7a4, WNOHANG, NULL) = 0 sigreturn() = ? (mask now []) close(4) = 0 close(9) = 0 write(2, "Got unusable memory address 0x40"..., 39Got unusable memory address 0x400cd008 ) = 39 _exit(1) End of strace. I would guess, this has something to do with different ELF-binaries, but anyone really knowing or guessing ? An other thing, the libtermcap (which the program unfortunatelly depends), has no libtermcap.so file, only those two files /lib/libtermcap.so.2 and /lib/libtermcap.so.2.0.8 installed by termcap-compat.
