Hi I've built gcc-30-cvs (20010508) with --with-dwarf2 on my IRIX 6.5.10 box. (This hint came from one of the gcc developers at Redhat) Using gdb-5.0-cvs (20010508) I get This GDB was configured as "mips-sgi-irix6.5"... (gdb) l 1 #include <iostream> 2 using std::cerr; 3 4 int main() { 5 cerr << "Hello world\n"; 6 } (gdb) b 5 Breakpoint 1 at 0x100010d0: file Hello.C, line 5. (gdb) r Starting program: /ARC/Tmp/Temp/a.out /usr/people/jarausch/ZIP/GNU/gdb-cvs/gdb-cvs/gdb/regcache.c:281: gdb-internal-error: legacy_read_register_gen: Assertion `regnum >= 0 && regnum < (NUM_REGS + NUM_PSEUDO_REGS)' failed. An internal GDB error was detected. This may make further debugging unreliable. Continue this debugging session? (y or n) n Is it a problem with gdb or g++ or both?
