Source: guile-3.0 Version: 3.0.4-3 Severity: normal Dear Maintainer,
Since version 3.0.4-1, guile-3.0 fails to build due to segmentation faults in libguile. See: https://buildd.debian.org/status/logs.php?pkg=guile-3.0&arch=hppa The first fault is here: Core was generated by `/home/dave/debian/guile-3.0/guile-3.0-3.0.4/libguile/.libs/guile -e (@@ (guild)'.

Nominally, exp points to a char, yet the generated code implies that exp points to a word that contains a pointer to some flag bits.
