Description Michael Link 2004-05-17 19:12:55 UTC 
Internal compiler error when compiling OpenSSL 0.9.7d. I didn't encounter this
error when using -Os.

X.org file, reduced to minimum reproducing bug

I spent some time reducing the size of this file to the bare minimum that
reproduced the bug, most of it is just includes defining X11 types which are
referred to in the 2 functions.

The bug seems very convoluted, removing a single for loop or printf often got
rid of the error

I'm using a cross compiler produced with crosstool by Dan Kegel (crosstool 0.28
rc23 for the default arm target) this uses gcc 3.4.0 and glibc 2.3.2
Comment 3 Richard Earnshaw 2004-08-05 11:00:00 UTC 
Confirmed, but already fixed in 3.4.1.
