RStudio core dump when querying sqlite DB

rstudio

#1

Looking for assistance with an RStudio core dump.

RStudio version 1.1.383 (Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/538.1 (KHTML, like Gecko) RStudio Version/7.0 Safari/538.1 Qt/5.9.4)
Unable to write a diagnostics report because it core dumps when I attempt it, stack trace as follows...

RStudio built with debug symbols (Gentoo x64 system, nearly everything is built from source).
Happy to provide additional info, on request.

Code that causes the core dump...

rm(list=ls());
library("RSQLite");
dbfile = "/tmp/usb_database.db";
sqlite = dbDriver("SQLite");
mydb = dbConnect(sqlite, dbfile);
dbListTables(mydb);
results = dbSendQuery(mydb, "select count(1) from DATA;")
<<coredump>>

The SQLite database is version 3.x last written with SQLite version 3008000 and works just find when using SQLite Studio 3.1.1 to execute the same SQL.

#2

It appears this is related to locale, I tried fiddling with my locale, C, en_AU.utf8, etc, no success.
(I set the locale, sourced /etc/profile again, ran rstudio at the command line, executed my test code, watched the crash).
I will admit, in wtf/unicode/icu/CollatorICU.cpp as a part of WebKit, the assert is immediately before a 'FIXME' comment....


#3

One other thing worth pointing out: RStudio typically bundles + uses its own copies of Qt + Boost; however, on your system it looks like they're being pulled out of the system folder. The binaries of RStudio v1.1 we distribute are built against a pretty old version of Qt (5.4.x) so mixing and matching Qt versions could lead to issues of this form.

For what it's worth, with RStudio v1.2 we plan to upgrade to the latest version of Qt possible (likely Qt 5.10 or 5.11). Our builds from https://dailies.rstudio.com use Qt 5.10.1; you might want to give one of the recent builds there a try.


#4

Thanks for the reply, the only problem is Gentoo builds RStudio from source, I don't use pre-built binaries.
So, it's a matter of using the correct branch in Github to retrieve the 'daily' source so I can build it.
So, going from github branch 1.2.9, it still core dumps.

#5

RStudio v1.2 builds are built from the master branch on GitHub, but please note that our binaries also use dependency installer scripts to ensure that we build against (and package) certain versions of our dependencies, e.g. Qt and Boost. (We're currently attempting to maintain compatibility with Qt 5.10+, and Boost 1.63+)


#6

Stand alone installerless daily build runs fine, I suspect my problem is I only have Qt 5.9 installed, whereas I do have Boost 1.65 installed.
