bash$ ./gdb -nx ... 7.2.50.20100817-cvs (gdb) p 0x1.1 ../../../src/gdb/gdbtypes.c:1385: internal-error: check_typedef: Assertion `type' failed. A problem internal to GDB has been detected, further debugging may prove unreliable. Quit this debugging session? (y or n)
Related problems: (gdb) set lang java (gdb) p 1.1f Invalid number "1.1f" (gdb) set lang pascal (gdb) p 1.1f Invalid number "1.1f". These are also due to invalid suffix handling in the language's respective parse_number routines.
