Your original backtrace was Error termination. Backtrace: #0 0x7f25c93aadf1 in ??? #1 0x7f25c93ab939 in ??? #2 0x7f25c93abe60 in ??? #3 0x7f25c960ce53 in ??? #4 0x401267 in ??? #5 0x4012c4 in ??? #6 0x7f25c903a041 in __libc_start_main at ../csu/libc-start.c:308 #7 0x4010ad in ??? #8 0xffffffffffffffff in ??? I would expect a long backtrace under gdb. Don't know what [Inferior 1...] means.
