This was introduced in 7.2 with support for ADL. Looks like a bug in types_equal, which doesn't account for cv qualifiers. >> Saurabh> 2. print k >> Saurabh> Let's say this prints 0x7ffb24 >> Saurabh> call fn2(0x7ffb24) >> Saurabh> gdb again says: Cannot resolve function fn2 to any overloaded instance >> Saurabh> This also used to work with gdb 7.2.

If you disable it ("set check type 0"), it should work: (gdb) p fn2(0x7fffffffde14) Cannot resolve function fn2 to any overloaded instance (gdb) set check type 0 (gdb) p fn2(0x7fffffffde14) 3 $7 = void Keith
