Didn't throw a segfault for me (same debian+libc-client, only 32bit), instead (with trunk) I got this (configure exited with code 1):

checking for U8T_DECOMPOSE...
configure: error: utf8_mime2text() has new signature, but U8T_CANONICAL is missing. This should not happen. Check config.log for additional information.

In config.log I have:

| #define HAVE_IMAP 1
| #define HAVE_NEW_MIME2TEXT 1
| /* end confdefs.h.  */
|
| #include <c-client.h>
|
| int
| main ()
| {
|
|          int i = U8T_CANONICAL;
|
|   ;
|   return 0;
| }
configure:49601: result:
configure:49606: error: utf8_mime2text() has new signature, but U8T_CANONICAL is missing. This should not happen. Check config.log for additional information.

This doesn't look like a PHP issue, but anyhow, is that still an
issue with any of the actively supported PHP versions[1]?
