Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.


As you can see, there are "???:0"s instead of sources and line numbers.
Maybe the gcc on my os doesn't comtain debug information.

Do I need to rebuild it with debug enabled?

I can reproduce with:

$ cat test.cpp

module;

#include <boost/asio.hpp>

export module foo;

Confirmed, reduced test-case:

$ cat pr102098.ii
module;
# 1 "" 1 3
struct Trans_NS__V2_error_category {
  virtual equivalent();
};
struct error_condition {
  Trans_NS__V2_error_category &category() const;
};
struct error_category {
  friend Trans_NS__V2_error_category const &to_std_category();
};
template <typename> struct _Rb_tree_iterator {
  typedef _Rb_tree_iterator _Self;
  friend operator==(_Self, _Self) {}
};
template <typename _Val> struct _Rb_tree {
  typedef _Rb_tree_iterator<_Val> iterator;
};
template <typename _Key, typename> struct map {
  typedef typename _Rb_tree<_Key>::iterator iterator;
};
struct std_category {
  bool equivalent(const error_condition &) const;
};
map<const error_category *, int>::iterator __trans_tmp_2;
inline Trans_NS__V2_error_category const &to_std_category() {
  map<const error_category *, std_category>::iterator i;
  i == __trans_tmp_2;
}
inline bool std_category::equivalent(const error_condition &condition) const {
