[R-sig-Debian] Querying sqlite through RODBC causes R to crash

[Tom Gottfried]

Dear R-SIG-Debian,

while trying to query data from an SQLite database through RODBC on 
Debian testing, R crashes with the following message:

library(RODBC)
con3 <- odbcConnect("test3")
# 'test3' being an ODBC datasource configured with SQLite3 driver,
# but the same happens with SQLite driver
sqlQuery(con3, "select * from test") # 'test' being any table

  *** caught segfault ***
address 0x438, cause 'memory not mapped'

Traceback:
  1: .Call(C_RODBCQuery, attr(channel, "handle_ptr"), 
as.character(query),     as.integer(rows_at_time))
  2: odbcQuery(channel, query, rows_at_time)
  3: sqlQuery(con3, "select * from test")

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Selection: 1
aborting ...
Segmentation fault



This is what sessionInfo says:

R version 2.15.1 (2012-06-22)
Platform: x86_64-pc-linux-gnu (64-bit)

locale:
[1] C

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base

other attached packages:
[1] RODBC_1.3-6



I tested the same under Windows 7 with the same sqlite-file without any 
problem. sessionInfo for the Windows-system:

R version 2.15.1 (2012-06-22)
Platform: x86_64-pc-mingw32/x64 (64-bit)

locale:
[1] LC_COLLATE=German_Germany.1252  LC_CTYPE=German_Germany.1252
[3] LC_MONETARY=German_Germany.1252 LC_NUMERIC=C
[5] LC_TIME=German_Germany.1252

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base

other attached packages:
[1] RODBC_1.3-6

loaded via a namespace (and not attached):
[1] tools_2.15.1



On the Debian system, both R and RODBC were installed from the Debian 
repositories. I also tried with an RODBC build from source with the R 
mechanisms (install.packages()), which results in the same error.

Any idea what is the cause or how I could sort it out?

Thank you very much!
Tom
