 As for other similar PRs, the only way to go is to reproduce the bug with an
 older compiler, trim down the preprocessed source to a bare minimum and
 eventually try again with mainline. Until we can properly check with
 mainline, it's a bit risky to close the PR.

 Hello,
 
 could the submitter please verify whether this bug appears in a more  
 current version of gcc (ie 3.2.3). Thanks,
 
 Dara

 Hi all
 
 the testcase in this PR no longer crashes as reported on gcc 3.3. On  
 powerpc-apple-darwin6.5 x hppa2.0w-hp-hpux11.00 cross compiler on 3.3  
 cvs (20030506) I get no errors. Unfortunately the testcase does not  
 compile at all on 3.4 due to changes in the C++ parser. With 3.4 I get:
 
 bash-2.05a$ /usr/local/lib/gcc-lib/hppa2.0w-hp-hpux11.00/3.4/cc1plus  
 -quiet -W -O2 -fPIC qinputcontext_x11.ii

 I'm not sure if this PR should be kept open or not, but it looks like  
 changes in 3.4 mean the provided preprocessed source isn't a valid  
 testcase, so we need an updated one.

 Hi all,
 
 using latest gcc 3.3 cvs and a darwin x
 hppa2.0w-hp-hpux11.00 cross compiler I was unable to
 reproduce the problem reported in this PR. The
 testcase takes a bit of time to compile, but does not
 ICE either at -O0 or -O2. Perhaps the problem has been
 fixed?
 
 Dara

Re: optimization/5415: [hp-ux] -O2 crash in redirect_edge_and_branch

[bangerth]

Old Synopsis: 3.1 0114 cvs g++ -O2 crash, on hp11
New Synopsis: [hp-ux] -O2 crash in redirect_edge_and_branch

State-Changed-From-To: open->feedback
State-Changed-By: bangerth
State-Changed-When: Sat Mar 15 04:31:39 2003
State-Changed-Why:
    Is this still an issue with newer versions of gcc? I don't
    have an hp-ux machine, but can't reproduce this on x86
    linux, so better ask.
    
    Thanks
      Wolfgang
