gcc v 2.95.2 on sparc-sun-solaris2.6 crashes with internal error

[Colin Surprenant]

gcc -v :
Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.6/2.95.2/specs
gcc version 2.95.2 19991024 (release)

uname -a :
SunOS sr0.mb.monsieur.net 5.6 Generic_105181-20 sun4m sparc
SUNW,SPARCstation-20

Bug triggered by:
gcc -g -O2   -c -o mbx.o mbx.c

mbx.c: In function `mbx_hdrpos':
mbx.c:1371: internal error--unrecognizable insn:
(insn 78 76 80 (set (reg:SI 129)
        (minus:SI (const_int 4 [0x4])
            (const_int -4096 [0xfffff000]))) -1 (nil)
    (expr_list:REG_EQUAL (const_int 4100 [0x1004])
        (nil)))

Bug solved with this patch on mbx.c :

1336c1336,1337
<     LOCAL->buf = (char *) fs_get ((LOCAL->buflen = HDRBUFLEN) + SLOP);
---
>     LOCAL->buflen = HDRBUFLEN;
>     LOCAL->buf = (char *) fs_get (HDRBUFLEN + SLOP);


For you info, the package is UW-IMAP found at
