R data inspection under gdb?
...ithin C code?
BTW, I'm familiar with the advice to use R_PV given in Writing R Extensions,
but it's not working for me. E.g., I get
(gdb) p R_PV(x)
$1 = void
and yet
(gdb) p *x
$2 = {sxpinfo = {type = 16, obj = 0, named = 0, gp = 0, mark = 0, debug = 0,
trace = 0, spare = 0, gcgen = 0, gccls = 1},

Helping out - simple bugs to help familiarize with R design, source, etc
Hi All,
Well I finally have found the time to get svn working and I have
successfully built my own tuned atlas (multi-threaded version) libs
and have both the r-devel and r-patched trees building daily on my box.
The problem is I still do not have a good idea of the layout and
design of R, and typically I "learn by doing" by trying to fix a bug
that hits me. Unfortunately ;-)

reproducible segmentation fault caused by textConnection()
Dear all,
It seems that textConnection() can trigger a segmentation fault. The
following script (using two large loops) makes this bug reproducible:
for (i in 1:10000) {
z=textConnection(NULL,open='w')
for (j in 1:100) {
write(runif(1)*1e6,file=z)
write('\n',file=z)
}
close(z)
}
The bug could be reproduced on R-2.6.1, R-2.7.0 and on the latest
R-devel
