Does bitcoind not support txindex=1 option in regtest mode?

Is it possible to specify txindex=1 option in bitcoin.conf or elsewhere? It doesn't seem to work. Whenever I run bitcoind -daemon, it stops.

If I remove txindex=1 from the conf file, it works.

I am using regtest mode.

Here is the conf file:

rpcuser=abc
rpcpassword=secret
regtest=1
rpcport=8332
txindex=1
