Ian Lance Taylor <ian at airs dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ian at airs dot com --- Comment #2 from Ian Lance Taylor <ian at airs dot com> --- Thanks for the bug report. I can't see any relevant change in libbacktrace. As far as I can tell the call to getpagesize has been there for a while, and the use of -Werror has been there for a while. Does mingw-w64-gcc have a getpagesize function? What header file declares it? Normally it is declared in <unistd.h>, but mmapio.c does #include that file.
