It is expected that gdb reports errors in an attempt to use them. GDB 7.3 reports such errors as expected GDB 7.4 crashes Attached is a simple pascal program, and the exe compiled with fpc 2.4.4 (must be 2.4.4 / other fpc do not generate the required broken dwarf) The source was compiled using: fpc.exe -gw hello.pas GDB was downloaded from http://www.drangon.org/mingw/ mingw-w64-bin-x86_64-20120225.7z : native mingw-w64 toolchain under Windows XP/2003 x64, build (gcc 4.6 branch) from SVN 2012-02-25 (29M) http://www.drangon.org/mingw/mirror.php?num=2&fname=mingw-w64-bin-x86_64-20120225.7z Run gdb as follows: gdb.exe -i mi hello.exe Then enter -break-insert main this crashes gdb 7.4 While this is primarily an issue of fpc and while such a broken file can not be debugged, it still should not lead to a crash. Especially since previous gdb versions were able to detect the error -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
