Susan Hinrichs commented on TS-1254:
------------------------------------
Set up a plugin that removes a field and then destroys it. Saw no assert.
Walked through the code as well and the second detach is the
mime_hdr_field_detach is indeed being called and catching things before the
is_alive is checked.
I assume this was fixed sometime along the way from 3.x to now.

> ts.h indicates that if you wish to destroy a "removed" header you should call
> TSMimeHdrFieldDestroy and TSHandleMLocRelease, however when --enable-debug is
> passed to configure the following assert is hit:
> {noformat}FATAL: MIME.cc:1496: failed assert `field->is_live()`{noformat}
> it seems that this assert would trip for any call to mime_hdr_field_delete if
> the field was previously detached.
