Summary: system(NULL) generates SIGSEGV
Product: Wine
Version: 1.1.41
Platform: x86
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: msvcrt
AssignedTo: wine-bugs at winehq.org
ReportedBy: carlo.bramix at libero.it
When an application calls system(NULL) or _wsystem(NULL), a SIGSEGV is
generated.
Actually the code of _wsystem() does not check the value of cmd parameter as
described here:
Perhaps a better implementation would be something like to:
comspec = msvcrt_get_comspec();
if (cmd == NULL)
return (comspec == NULL) ? 0 : 1;
else
if (comspec == NULL)
return -1;
