gdb: Improve scoped_switch_fork_info class
After committing this patch I got this feedback:
https://sourceware.org/ml/gdb-patches/2019-01/msg00181.html
This patch makes the constructor of scoped_switch_fork_info explicit,
and wraps the core of the destructor in a TRY/CATCH block.
I've run this through the testsuite on X86-64/GNU Linux, however, this
code is not exercised, so this patch is untested.
gdb/ChangeLog:
* linux-fork.c (scoped_switch_fork_info)
<scoped_switch_fork_info>: Make explicit.
<~scoped_switch_fork_info>: Wrap core in TRY/CATCH.
