Status changed to 'Confirmed' because the bug affects multiple users.

I get a segfault on an Asus UL30A laptop (Genuine Intel(R) CPU U7300) which is 64bit and running Ubuntu Lucid 10.04 (updated to .2) but not under same OS on AMD Phenom II X6 1090T. Tried purging and reinstalling bibtool.

Suggestions for test cases welcome.

Further to above, I decided to get source (now version 2.53 while repository has 2.51) and built it. This did NOT give the segfault.

I get this error as well. Perhaps this is related to the static memory allocation? I seem to get this error with large bibfiles (e.g. ~1000 entries with abstracts)
