Description Traub, JT 1999-07-10 06:35:05 EDT
This appears also to be part of a larger problem.  egcs
included with RedHat 6 optimizes a function in such a way
that called from certain places, the return value is
smashed.  This causes Pine to correctly report to the local
user that a file is of one MIME type, but end up attaching
it as the default for the type.  (E.g. text/* becomes
text/plain, etc.)  To reproduce this bug, compile Pine from
the SRPM on RedHat 6 with egcs-1.1.2-13 (RPM, egcs --version
shows 2.91.66).  This bug ALSO occured on a Linux 1.2.x
system using gcc-2.7.2 on RedHat 3.0.3 (just to show it's
apparently a long-standing bug).

Adding a sleep(0) call above the return in the problematic
function is a solution to this problem.  See the attached
URL.

While this should probably be fixed in PINE in the
short-term, long term it probably points to something
needing to be seen to in egcs.  IT IS WORTH NOTING THAT THIS
BUG OCCURED WITH ALL OPTIMIZATIONS OFF.  This bug has been
logged against Pine as well.
