Turns out the problem is with glib. g_slice_new0() in __qmi_indication_nas_serving_system_indication_parse() returns a misaligned memory block, contrary to what the glib documentation says. Turning off glib's 'magazine layer' seems to avoid this problem. This can be done by calling g_slice_set_config(G_SLICE_CONFIG_BYPASS_MAGAZINES, TRUE); Note that g_slice_set_config() is flagged as deprecated, so it may be necessary to patch glib/gslice.c instead. Is there an open glib bug for the alignment issue? Would be nice to track it and make sure it gets fixed, or know what version it was fixed in if others encounter this. |

I've just started to use libqmi on an AM335x platform (ARM Cortex-A8) with a Sierra MC7354 module. Under certain circumstances I'm getting an 'Alignment trap' error which causes the kernel to send SIGBUS to my application. I can reliably trigger the error by having my application do the following: - setup a callback for NAS Serving System Indications (to detect registration state) - establish an LTE connection - disconnect the antenna from the module to trigger loss of registration - re-connect the antenna to re-register When re-registration occurs, there are typically a few 'Serving System' indications and this will trigger the problem. Note that I can leave the system online for hours with numerous prior 'Serving System' indications without any problems. However, if I disconnect and reconnect the antenna (and thereby force a loss of registration) the problem occurs reliably every time when the cell module re-registers. I started out with libqmi 1.16 and glib 2.37 and then upgraded to libqmi 1.17.900 and glib 2.50.2, but nothing changed. Here is the syslog showing the whole antenna disconnect/reconnect sequence. GDB output is below. Any help would be greatly appreciated!
