If Coro causes segfaults a lot on calls to libc functions, the cause is |
| 2 |
probably a glibc compiled for i386 and kernel 2.2. |

|
| 4 |
Glibc contains a bug that causes any program linked against pthreads AND |
| 5 |
using coroutines (of any kind, not only Coro) or alternate stacks to |
| 6 |
segfault on calls to pthread functions. And glibc happens to do a lot of |
| 7 |
these calls. |

The bug is rather difficult to fix. This is not a problem, however, since |
| 10 |
glibcs compiled for linux-2.4 use a much more efficient method to locate |
| 11 |
their data, which happens to work tiwh coroutines. |
| 12 |
|
| 13 |
So the easy fix is to install a libc which was compiled for linux-2.4, |
| 14 |
using the --enable-kernel=2.4 configure option. WARNING: This kernel will |
| 15 |
no longer run on linux-2.2 or lower! |
