Justin, I just read back in the thread and saw that you already
described a fix in English, and asked for a patch. I will [have to]
tackle to fix this as soon as I am going to do some coding on svn
again. But it would of course be much more convenient for me if the
problem was fixed before then.
Another note for clarity:
My self-compiled APR is 1.3.3.
The OS-provided one is 1.2.11.
The crashing code is #ifdef'd for 1.3.0 and upwards:
* N.B. If we have APR 1.3+, we can unbuffer the file to let us use mmap
* and zero-copy the PUT body. However, on older APR versions, we can't
* check the buffer status; but serf will fall through and create a file
* bucket for us on the buffered svndiff handle.
*/
apr_file_flush(ctx->svndiff);
#if APR_VERSION_AT_LEAST(1, 3, 0)
apr_file_buffer_set(ctx->svndiff, NULL, 0);
#endif
At compile time the compiler sees APR 1.3.3, but at run time
1.2.11 is loaded. Hence the crash.
