Follow-up Comment #1, bug #64730 (project groff): This is probably a bug in the gcc with one of the options -fsanitize=undefined, -fsanitize=bounds, and -fsanitize=bounds-strict, as the error is absent with default flags "-g -O2".
This default warning remains: warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings] The line number and name of the source file is missing in the error message: GROFF doc/pic.html failed to replace fd=1 with -1 pre-grohtml: fatal error: dup2: Bad file descriptor and GROFF doc/webpage.html failed to replace fd=1 with -1 pre-grohtml: fatal error: dup2: Bad file descriptor _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?64730> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
