Compilation works fine, the executable segfaults, due to a stack overflow.
The standard says your code is "ill-formed, no diagnostic required" so
compilers aren't required to reject the code, but it would be nice to diagnose
it.
Clang does:
circ.cc:10:7: error: constructor for 'T' creates a delegation cycle
[-Wdelegating-ctor-cycles]
: T(i,s)
^
circ.cc:3:5: note: it delegates to
T(const int i,
^
circ.cc:8:5: note: which delegates to
T(const char * s,
^
And EDG does:
"circ.cc", line 10: error: constructor delegates directly or indirectly to
itself
: T(i,s)
^
