Follow-up note - distro-provided bc on Arch does work. I was previously only testing my own build against latest sources from ftp.gnu.org. Should be possible for us to compare/contrast and figure it out. Thanks for the report. -Rob On 3/7/16, 3:13 AM, "Dev on behalf of Nesius, Robert A" <dev-bounces(a)lists.clearlinux.org on behalf of robert.a.nesius(a)intel.com&gt; wrote: > >Whatever is happening on line 68 of load.c is broken on multiple platforms. > >Not sure what the root cause is but I repro'd it on Clear Linux and Arch Linux (32-bit and 64-bit). > >Hmm... I see a memory-leak patch for bc out in the wild, but that didn't look like a smoking gun. I did wonder based on comments I read in source if "bc -l" might run into problems when working with a version of libm that had symbols stripped, but I just did some test-builds to explore that thought and came up blank. > >I'll try to look at this memory leak patch in the next day or so - it didn't apply cleanly for me. > >-Rob > > > > > >On 3/7/16, 1:35 AM, "Dev on behalf of Jan Fikar" <dev-bounces(a)lists.clearlinux.org on behalf of j.fikar(a)gmail.com&gt; wrote: > >> >>> I'm getting segmentation fault using "bc -l" to calculate for example 3*3 in Clear Linux 6580, details are below.
