And another one :-(
We have a bug report, where doing "break file:line" inserts 13 breakpoints
with GDB CVS, but only 9 with GDB-6.8.
The problem is that the extra 4 insertions are all in the middle of
instruction(s), and cause inferior to SIGSEGV if any of these instructions
is ever executed.
This is happening in a large piece of optimized code, still working on
reduced test case. Analysis so far:
The problem appears to be in expand_line_sal(). Both gdb-6.8 and gdb-cvs
construct a list of 20 candidates, but then gdb-6.8 filters that list down
to 9, and gdb-cvs down to 13 candidates.
