Bug #: 50932
Summary: inserting a gimple_call with gsi_insert_after creates
error in remove_unreachable_handler
Classification: Unclassified
Product: gcc
Version: 4.5.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: leppkes@stce.rwth-aachen.de
Created attachment 25673
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25673
plugin.c with Make and testfiles.
I want to create calls to my instrument functions. Therefor i'm writing a gcc
plugin.
Before and after function is called, i want to call my instrument function.
Inserting a gimple_call before the statement is no problem, but inserting after
creates the following bug:
"[...] internal compiler error: in remove_unreachable_handlers, at
tree-eh.c:3299"
See the attached tarbal:
- The insert_debug2 function inserts a gimple_call after the actual call in the
subroutine. The dump-files shows that the call is inserted corretly, but then
the compiler crashes.

You have issues with exception regions. I think you should mark the dco
functions as nothrow and handle the case where the function are inserting after
a function which could throw.
