Dear Maintainer,
To debug large complex programs that use guile extensions, I run `gdb
guile` regularly. This does not work w/ current version in testing. I
get this:
```
$ gdb guile
GNU gdb (Debian 12.1-3) 12.1
... etc ...
Reading symbols from guile...
(No debugging symbols found in guile)
(gdb) r
Starting program: /usr/bin/guile

Looking at the above stack trace, I suspect the issue is actually with
bdwgc ... unless guile is doing something wacky with stacks before
initing bdwgc. I guess this could also be a gdb bug!??
Of course, guile itself works just fine -- it only crashes when starting
guile from gdb! So that is ... confusingly bizarre.
For me personally, tis is a critical bug; I depend strongly on having
gdb working correctly.
