Like a couple of other posters in the past year, I was seeing R 2.8.1
segfault in the foreign package on my Solaris 10 Intel system:
> library(foreign)
*** caught segfault ***
address fe1d5c70, cause 'invalid permissions'
Traceback:
1: .C("spss_init", PACKAGE = "foreign")
2: fun(...)
This happened whether I built with gcc3, gcc4, or SunStudio 12.
Using pstack I found that the code was crashing in avl_create().
Using truss I found that identically named functions in the Solaris
/lib/libavl.so.1 library were being used instead of the AVL functions
provided in avl.c in the foreign package. To verify, I replaced all
of the "avl_" and "AVL_" patterns in foreign/src/*.[ch] with "ravl_"
and "RAVL_" respectively. Once I made this change, loading the
foreign package caused no further problems.
An alternative workaround was a hack involving symlinks and
LD_LIBRARY_PATH, but that was not satisfactory. Since the foreign avl
functions are incompatible with the ones provided by the standard Sun
library, this approach has other potential gotchas.
FYI.
Jeff
