| 2 | I have received bug reports about dump telling that dump receives | |
| 3 | unexpected signals when dump directories (in pass III). I have tried to | |
| 4 | reproduce the problem and it appears that this may be caused by an optimization | |
| 5 | problem in some versions of gcc. Dump works fine when compiled with | |
| 6 | optimization by gcc 2.6.2 but it fails when compiled by gcc 2.6.3: | |
| 7 | - either it gets an unexpected signal (SIGFPE), | |
| 8 | - or it issues warnings ``Warning: dumpdirino called with file type | |
| 9 | 040000'' and does not dump directories. | |
| 10 | ||
| 11 | I am not courageous enough to study the assembly code generated by | |
| 12 | gcc (yet :-), so I have modified the Makefiles to compile dump without | |
| 13 | optimizations. I have also fixed a few minor bugs and removed some printf's | |
| 14 | that I had added during my tests. I will study the assembly code generated | |
| 15 | by gcc soon and fix the problem. | |

| 17 | The fixed version (numbered 0.2a) is now available on tsx-11.mit.edu | |
| 18 | in the directory /pub/linux/packages/ext2fs. Please get it if you are using | |
| 19 | dump and restore. | |
