[Chicken-users] Segmentation violation with chicken 5.1.0

[Sven Hartrumpf]

Hello.

I have a strange problem with legacy code that works in many
other Schemes and Chicken 5 csi, but the binary compiled with Chicken 5 crashes.
I have a reduced example: http://sempria.de:9080/resources/chickenprob3.tar.bz2
Just unpack and type make in the resulting directory.
It shows "Error: segmentation violation" with gcc 8.3.0 and 9.1.0, 64 bit,
Ubuntu 19.04.
Interesting effect: the crash goes away if the input data structure is reduced
after reading by passing a CLI argument smaller than 228,
see makefile target 'check'.

Can anybody reproduce this segv?
