Core dumps broken with libffi? |

I recently switched from gnustep-base 1.30.0 and ffcall to gnustep-
base 1.18.0 and libffi. Everything seems to work OK, except that when
a program dumps core in the new environment, gdb is unable to display
anything useful (like a stack trace) from the core dump; the errors
vary, but here's one example:
gdb> bt
#0 0x40b3cc30 in poll () from /lib/libc.so.6
Cannot access memory at address 0xbf3ff8d8
gdb>
This on x86 linux 2.4, with both gdb 6.4.90 and 6.6. If I run the
program under gdb and it aborts, everything is fine; it's just core
dumps that are broken.
Has anyone else run into this?
