Description Brett Foster 2005-10-09 02:26:29 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4

Description of problem:
While compiling an application I wrote for GCJ, I get a segmentation fault when linking a class file to an object file. GCJ 3.xxx from FC3 operated without fault.  The class itself is pretty simple and straight forward. If I comment out the file, the next file seg faults, and so on...

Version-Release number of selected component (if applicable):
gcc version 4.0.1 20050727 (Red Hat 4.0.1-5)

How reproducible:
Always

Steps to Reproduce:
1. Download jjtag ( http://www.ioware.ca/projects/ejtag/jjtag.tgz )
2. perl configure.pl > Makefile
3. make
  

Actual Results:  [fosterb@localhost jjtag]$ make

Comment 1 Christian Iseli 2007-01-22 11:41:38 UTC

This report targets the FC3 or FC4 products, which have now been EOL'd.

Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?

Thanks.

I grabbed:
  http://www.ioware.ca/projects/ejtag/1.0.0/jjtag.tgz
I tried with gcc svn trunk and this worked fine.
I also tried with the FC-6 gcj and I got link errors,
but no compiler ICE.  So, I am closing this.
Please reopen if you think this is in error.
