            Bug ID: 20332
           Summary: CU DIEs for assembly files cause debug info truncation
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: DebugInfo
          Assignee: unassignedbugs at nondot.org
          Reporter: compnerd at compnerd.org

If you have three TUs:

a.c: int a(void) { return 65; }
b.S:

    .def _b
      .scl 2
      .type 32
    .endef
  _b:
    movl %eax, $66
    ret
c.c: int c(void) { return 67; }

Compiling them for i686-windows-{itanium,gnu} with debug and link them, CUs
including the first assembly input will be truncated in the debug info output.

This is a regression from 3.4.
