Shortest known program to cause over 1,000 lines of error messages in gcc.
Raw
1k_errors.cpp
// C++ error messages are notorious.
// Some folks and I worked on a golf challenge: Shortest program to produce more
// than a thousand lines of error messages in gcc.
// Constraints: gcc >= 8, no -fmessage-length
// Fueled by the decltype(decltype) bug discovered by Jonathan Wakely (detailed
// at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92105), this is the current record
// 32 characters:
#define d decltype
d(d(d(d(d))))
