Re: [Chicken-hackers] NetBSD w/ 4.8.0rc3

[Timo Myyrä]

Hi,

I tested this on my OpenBSD 5.2-current (amd64).
I run the symbolgc-tests as follows:
perl -e "system('./symbolgc-tests -:w > /dev/null') for (1 .. 100);"

And got segfaul on roughly each run except I also got 3 of these:

[panic] out of memory - cannot allocate vector (heap resizing
disabled) - execution terminated

...more...
symbolgc-tests.scm:17: display
symbolgc-tests.scm:17: get-output-string
symbolgc-tests.scm:17: string->symbol
