Running valgrind on GnuCOBOL errors out with

at 0x4E75F20: cob_string_init (strings.c:742)
Using vgdb there were the following details:

133 Dump of assembler code for function cob_string_init:

Is there anything I can do this to still run the application with
valgrind or do I need to wait for a hotfix?
Thanks,
