--- Comment #14 from Matt Godbolt <matt at godbolt dot org> --- Created attachment 40101 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=40101&action=edit compile with gcc 6.2 -std=c++14 This reproduces the issue. Compile with g++ 6.2 and -std=c++14 to create a file which contains the symbol: _ZSt7forwardIR17predicate_matcherIZ11any_matcherIiEDavEUlOT_E_13typed_matcherIiEEES3_RNSt16remove_referenceIS2_E4typeE This symbol crashes both c++filt (2.26.20160125) and gdb (7.10) in the same way as this bug describes (d_print_comp infinite recursion).
