[gccsdk] [Bug 242] New: Segfault from asasm

http://www.riscos.info/bugzilla3/show_bug.cgi?id=242

Summary: Segfault from asasm
Product: GCC/GCCSDK
Version: other
Platform: All
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P1
Component: RISC OS-specific tools
AssignedTo: John.Tytgat@aaug.net
ReportedBy: gccsdk-bugzilla@markettos.org.uk
Estimated Hours: 0.0


I have a checkout of GCCSDK rev 5827 which is giving a segfault when I try to
assemble something. To reproduce this:

git clone git://github.com/caliston/ro-bootlinux.git
cd ro-bootlinux
git checkout 4e3b87b8f6
cd HAL
../../../gccsdk/cross/bin/asasm -o Messaging.o s/Messaging
Segmentation fault

I can't update to HEAD (5890) because that won't build either (build error
below).

gdb backtrace (I'm not entirely sure what's going on here):
