fwrite "segfault from C stack overflow" for very wide (1,344,389 column) DT #1903
I am using the latest development version of data.table and when I am trying to fwrite a huge table, it errors out with the message "segfault from C stack overflow".
The github version which I installed two weeks back on another system is working perfectly for the same file.
Could you please fix this?
If you are on Windows please ensure to purge the old version fully. Maybe reboot required, even these days. We've seen problems before where Windows appears to keep the old .dll hanging around. When this happens it causes segfault as you described. Also, please try the very latest version as of today as there have been changes in the last few days. (The verbose=TRUE output will give me more info now, for example, if you can provide that.)
Sorry about the lack of clarity.
