[Bug c/20141] New: crashing the compiler with -03

[stephane dot bosio at vendeeconcept dot com]

making a simple standalone/embedable editor I fall on a strange behavior.
code crashing the compiler with -03 level of optimisation, no complaints with -
O2
It's still very bugged, but it's a pre_alpha code
this is quite a small programm
(less than 4000 words in the .i file)
should be good for tracking

[Bug middle-end/20141] [3.4, 4.0 regression] ICE on bad prototype at -O3

[falk at debian dot org]

------- Additional Comments From falk at debian dot org  2005-02-22 13:40 -------
Confirmed, this is an ICE on invalid code. This is a test case for 4.0 (but
for some reason it doesn't work for 3.4):

struct ED_Ligne { int x; };
void dealloue_ligne();
void dealloue_buff(struct ED_Ligne *tab_lignes) {
    dealloue_ligne(*tab_lignes);
}
void dealloue_ligne(struct ED_Ligne *lig) { } 

% gcc -O3 -c test.c
test.c: In function 'dealloue_buff':
test.c:4: internal compiler error: in fold_convert, at fold-const.c:1922
Please submit a full bug report,
with preprocessed source if appropriate.

Basically this is the same as PR 16876.
