[MIT-Scheme-devel] problem building on Linux ARMv71

[Sam Jessup]

Here’s my setup:

$ uname -srmo

Linux 3.8.13-25-ARCH armv71 GNU/Linux

$ gcc -v

Using built-in specs.

COLLECT_GCC=gcc

COLLECT_LTO_WRAPPER=/usr/lib/gcc/armv7l-unknown-linux-gnueabihf/4.8.2/lto-wrapper

Target: armv7l-unknown-linux-gnueabihf

$ pwd

Here’s the error:

$ ./etc/make-liarc.sh

...

Unhandled signal received within critical section "garbage collector".

Killed by SIGIOT.

*** Error in `../microcode/scheme' : munmap_chunk(): invalid pointer: 0xb50d8008 ***

It looks like scheme is breaking during initalization. With debugging enabled:

$ ./microcode/scheme --library ../lib --fasl "http://www.gnu.org/software/mit-scheme/lib/runtime/make.so" --heap 6000

MIT/GNU Scheme running under GNU/Linux

…

initialize: (runtime floating-point-environment)Error code 0xa (external-return)

Procedure was: [PRIMITIVE SET-TRAPPED-FLOAT-EXCEPTIONS]

# of arguments: 1

Return code: internal-apply

Error code 0x2 (unassigned-variable).

_expression_ was: [false 0x245f020]

Environment was: [false 0x1]

Return code: join-stacklets

… [repeated many times until segfault] …

The good news is that I managed to build a boot compiler by editing ./etc/build-boot-compiler.sh to run scheme inside valgrind…

Any suggestions about where to look for this bug?

Thanks,

Sam
