Bug#916626: qbs: FTBFS on hppa: Segmentation fault (core dumped)
Source: qbs
Version: 1.12.2+dfsg-1
Severity: normal
Dear Maintainer,
See build log:
https://buildd.debian.org/status/fetch.php?pkg=qbs&arch=hppa&ver=1.12.2%2Bdfsg-1&stamp=1544493575&raw=0
The fault is:
do_page_fault() command='QThread' type=15 address=0xedd80000 in libQt5Script.so.5.11.2[f645d000+214000]
trap #15: Data TLB miss fault, vm_start = 0xedd80000, vm_end = 0xedd81000
The TLB entry for the page is missing.
When the faulting program is run under gdb, we have:

The fault occurs loading the return value from QTJSC::Heap::markConservatively.
Possibly, this is bug in libqt5script5.
