Product: gcc
Component: gcc
Summary: gcc Internal compiler error in emit_move_insn_1, at
expr.c:3106
Version: 3.2-4mdk
Platform: PC
OS/Version: All
Status: UNCONFIRMED
Severity: major
Priority: P2
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
The problem is with gcc-3.2-1mdk (came with Mandrake 9.0), but I do not know
how to upgrade to gcc-3.2-4mdk; I would be happy for someone to tell me how to.
I got this error when compiling linux kernel 2.4.20 patched with linux-abi
2.4.18:
--------------------

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:https://qa.mandrakesoft.com/> for instructions.
--------------------
Attached is file sysi86.c. I have not included preprocessed output because it
was too large for Bugzilla to handle.
