Bug ID: 30713
Summary: do not catch 'const gdb_exception &'
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: tromey at sourceware dot org
Target Milestone: ---
Right now a fair amount of code looks like:
try
...
catch (const gdb_exception &)
... stuff
However,this can end up swallowing a QUIT if one is not careful.
I think it would be better to catch 'const gdb_exception_error &'
in nearly every spot.
One question is what to do with this:
struct gdb_quit_bad_alloc
: public gdb_exception_quit,
public std::bad_alloc
I don't know why it derives from the _quit form and not
_error. Perhaps that's fine, though, since it would just
end up returning to the top level.
