Bug#34452: Libguile4-dev breaks when libc is upgraded
Package: libc6-dev
Version: 1:1.3-12
Last evening, I upgraded a number of packages, including (I believe)
the libc6 packages. The libc6 packages are now at 2.1.1-0pre1. Ever since
then, any programs I compile locally which embed Guile segfault in
setvbuf(), called from gh_enter(). This goes for everything from
a short test program I wrote which does pretty much nothing but initialize
Guile, to Aisleriot (a solitaire game which uses Guile heavily) and an AIM
client which uses Guile. _However_, programs which were compiled before the
upgrade or installed as binary packages, such as the Guile interpreter
itself, still work, so I doubt that it's a problem with the runtime libraries.
The backtrace from a simple Guile-using program which basically just calles
gh_enter (I've attached the source):
bluegreen:~/tmp> gcc -o guile-test guile-test.c `guile-config compile` `guile-config link`
guile-test.c: In function `main':
guile-test.c:11: warning: passing arg 3 of `gh_enter' from incompatible pointer type
bluegreen:~/tmp> gdb guile-test

I think this is a libc6-dev problem, but it may be related to libguile4-dev
instead or even another package (I upgraded a few others).
Anyway, hope this helps so I can compile my Guile programs again! :-)
