 Yep.  We found this last week and I haven't gotten around to the fix
 yet but I'll try to make sure that's included in 6.8.

 Daniel,
 
     The problem is fixed in cvs.
 
     However, the cvs version won't build on Solaris. In remote.c line
 2859 the line "sprintf("vaAttach;%x", pid)" fails because (at least on
 Solaris) pid_t isn't unsigned and its using an unsigned format specifier
 for a signed long. The exact error message is:
 
     > remote.c: In function `extended_remote_attach_1':
     > remote.c:2859: warning: unsigned int format, pid_t arg (arg 3)
 
     I can file a bug if you want.
 
 Thanks,
 Gordon

 Try GDB HEAD, where this should be fixed by Vladimir's heroic work.

>Description:
If I create a C++ class and define the constructor outside
the class definition, breakpoints in the constructor are
ignored. Adding complexity to the constructor (I/O or function/method calls) resolves the problem.

Doing object file dumps of the debugging/line information
shows the object file has line information for the line
in question. The break commands also succeed. Its just at
run time the breakpoints are ignored.
>How-To-Repeat:
Set breakpoints at lines 7, 14, and 20. Run the program.
Gdb stops at the breakpoints at lines 7 and 20, but does
not stop at the one at line 14.
