Description
I just tried again to record flexirob data and this time another file recorded using a trunk version of bag-record is severely broken. The file will be attached to the bug.
flexirob@graphit:~/Desktop/rsbag$ ./bag-record --version
WARNING:
Failed to load Spread library: Unable to load any of the alternatives:
("libspread-without-signal-blocking.so" "libspread.so" "libspread.so.2"
"libspread.so.2.0" "libspread.so.1").
Did you set LD_LIBRARY_PATH?
Spread transport will now be disabled.
./bag-record version 0.7.0
SBCL version 1.0.57
RSB version 0.7.0
RSBAG version 0.7.0
RSBAG-TIDELOG version 0.7.0
The file date of bag-wth-rst is 2012-07-16 14:25, so I suspect I downloaded it at that time. Running on 32 bit, precise.
bag-record processes are terminated via a single call from kill (without -9). For all bag-record processes I can see this message when closing:
attempt to THROW to a tag that does not exist: ITERATE:TERMINATE.
This is reported for all bag-record processes but only some files are really broken.

I still have that version of bag available for testing.

This is basically a strange user error as my script produces several signals in rapid succession. However, shielding against such a case would be nice.
