Same here with HEAD and 1.8.0. Here's what happens:
#0 0x0fc13f6c in raise () from /lib/tls/libc.so.6
#1 0x0fc15a0c in abort () from /lib/tls/libc.so.6
#2 0x0ffa4a1c in scm_ithrow (key=0x10015410, args=0x300a2558,
noreturn=<value optimized out>) at throw.c:699
#3 0x0ff3718c in scm_error_scm (key=0x10015410, subr=0x300781f0,
message=0x300781d0, args=0x300a2578, data=0x4) at error.c:92
#4 0x0ff37220 in scm_error (key=0x10015410, subr=<value optimized out>,
message=0xffc5594 "Unknown option name: ~S", args=0x300a2578,
rest=0x4) at error.c:58
#5 0x0ff37268 in scm_misc_error (subr=0xfa <Address 0xfa out of bounds>,
message=0x3001bb60 "", args=0x0) at error.c:268
#6 0x0ff721a8 in scm_options (args=0x300a25e8, options=0xffe1b40, n=7,
s=0xffc117c "evaluator-traps-interface") at options.c:202
#7 0x0ff3a1e4 in scm_evaluator_traps (setting=0x300a25c8) at eval.c:3134
#8 0x0ff3ec50 in deval (x=<value optimized out>, env=0x300a2668) at
eval.c:4219
(Note the "Unknown option name"...)
And `(trap-enable 'enter-frame)' loops forever and yields a stack
overflow:
#0 scm_gc_mark_dependencies (p=0x3019b0b0) at gc-mark.c:199
#1 0x0ff4b6cc in scm_gc_mark (ptr=0x3019b0b0) at gc-mark.c:169
#2 0x0ff4b34c in scm_gc_mark_dependencies (p=<value optimized out>) at
gc-mark.c:218
#3 0x0ff4b6cc in scm_gc_mark (ptr=0x3019b0b0) at gc-mark.c:169
#4 0x0ff4b34c in scm_gc_mark_dependencies (p=<value optimized out>) at
gc-mark.c:218
[ repeated ad infinitum... ]
Deserves further investigation... ;-)
Thanks,
Ludovic.
