            Bug ID: 31896
           Summary: -exec-next skips statements
           Product: gdb
           Version: 14.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: dmitry.neverov at jetbrains dot com
  Target Milestone: ---

I'm debugging the following code, the at line1 (v =3D=3D 0):

  if (v) { // line1
    // branch1
  } else if (predicate()) { // line2
    // branch2
  }
  else=20
  {
    // branch3, line3
  }

When I issue the `next` command, execution stops at line3 instead of
line2. If I change the code and add a newline before the 'else if',
`next` stops at line2 as expected:

  if (condition1) { // line1
    // branch1
  }
  else if (predicate()) { // line2
    // branch2
  }
  else=20
  {
    // branch3, line3
  }

It looks like it happens because the last jump instruction in first
branch has the line2.

--=20
